Multiparameter Benchtop Meters Product Description
|
The ProLab 4000 professional multiparameter benchtop meters were designed to perfectly match SI Analytics world class conductivity, pH,
and ion selective electrodes. With a measuring range from 0.000 uS/cm to 2000 mS/cm, TDS and salinity measurement as well as
various functions for temperature compensation and setting up the cell constant the multiparameter benchtop meters set the standard for
professional instrumentation. In addition to the conductivity offering the multiparameter benchtop meters measure pH in the range
of -2.000 to +20.000 pH with an accuracy of 0.002 pH and 0.1 mV and an automatic temperature measurement range of -31 to 302 °F
(-35 to 150 °C).
Multiparameter benchtop meter pH electrode calibration check
The ProLab 4000 multiparameter benchtop meters achieve their accuracy by using a feature called CalClock. The CalClock feature
provides the multiparameter benchtop meters with a unique combination of sensor evaluation and a calibration timer which controls all
relevant calibration settings. The multiparameter benchtop meter's sensor evaluation displays the pH electrode's quality in
increments. The multiparameter benchtop meters monitor the pH electrode's slope, zero point, and reaction time. The selected
calibration interval is displayed by the multiparameter benchtop meter as a countdown in six steps as a set of circular segments around
the pH electrode which elapse proportionally to the calibration interval. When the time interval has elapsed the multiparameter
benchtop meter activates an optical and acoustic signal. The multiparameter benchtop meter's automatic calibration of up to 5 points
and automatic buffer recognition of 22 buffer sets guarantee trustworthy pH measurement results of the highest quality. The user
can employ his preferred buffers on the multiparameter benchtop meters the same comfortable way as the SI Analytics DIN buffers and thus
easily comply with the users specific SOP requirements. During the calibration process the multiparameter benchtop meter can display
either the buffer pH or the current mV value. The slope can be displayed in either % of in mv/pH and the asymmetry reading in mV or
pH on the multiparameter benchtop meter's display screen.
Multiparameter benchtop meter conductivity features
The ProLab 4000 professional multiparameter benchtop meter uses a special conductivity compensation procedure to eliminate potential
temperature and concentration errors. The conductivity measurement of an aqueous solution is subject to its temperature and the
concentration of dissolved substances in it. To compare conductivity measurement values which were taken at different temperatures
all measurements must be recalculated using the same reference temperature. The two common procedures for correcting conductivity
measurements, linear and non-linear (according to EN 27888), can only be applied to diluted measuring solutions, otherwise the concentration
dependency is not taken into account. Additionally the conductivity measurement temperature range should lie within ± 10K of
the reference temperature. The ProLab 4000 professional multiparameter benchtop meters eliminate these restrictions thanks to special
compensation procedures. The multiparameter benchtop meters procedures feature the following:
- Usage of two pre-programmed temperature coefficients for HCl, NaOH, NaCl and KCl for a temperature range of 32 to 104 °F (0 to 40 °C)
- Possibility of entering literature values for two temperature coefficients for additional solutions
- Determination of temperature coefficients by:
- Setting the temperature range and intervals
- Measurement of one or multiple solutions of known and even unknown concentrations (through equidistant dilution)
ProLab 4000 professional multiparameter benchtop meters are therefore qualified for use in science and for monitoring industrial process
applications. The multiparameter benchtop meter allows you to make high precision conductivity measurements over a wide temperature and
concentration range.
Multiparameter benchtop meter sensor and user recognition
The multiparameter benchtop meter's wireless sensor recognition and user identification features mean that every stored measurement can be
assigned an electrode and user ID. The multiparameter benchtop meter reads the electrode's individual data (slope, zero point, ID number,
and date of last calibration) directly from the special ID sensor. The ID sensor stores all new calibration data every time the sensor
is re-calibrated thereby assuring that only the most recent data is used by the multiparameter benchtop meter for calculation of the measured
value. No additional cables are required for the multiparameter benchtop meter to use the special ID feature, as the transponder is
mounted in the sensor's plug. This means that even when using multiple ID-electrodes on the same multiparameter benchtop meter, the
correct calibration data is always chosen automatically. The ID recognition process is performed automatically by the multiparameter
benchtop meters and does not require any manual settings. If sensors without the special ID function are used with the multiparameter
benchtop meters the sensor values are stored in the instrument, so existing sensors can be used without any issues.
The ProLab 4000 professional multiparameter benchtop meters also comply with further requirements by allowing you to set administrator rights
or set up user identification via an electronic ID card. A special key ring pendant with a transponder is utilized as an "ID card" to
identify registered users with the multiparameter benchtop meter. The pendant only needs to be placed onto the recognition field on the
upper side of the multiparameter benchtop meter. The transponder stores an individual 12 digit number that is read by the multiparameter
benchtop meter and assigned to each measurement and calibration. For full identification the additional entry of a password is required
to use the multiparameter benchtop meter. The multiparameter benchtop meter's administrator has rights to change this setting if full
identification is not required. The multiparameter benchtop meter runs the entire process automatically in the background and doesn't
require any user settings. Measurements and calibrations performed without prior user recognition are labeled by the multiparameter
benchtop meter as "anonymous" and can be sorted accordingly. Additionally, the multiparameter benchtop meter's sensor recognition records
the pH electrode used by the individual user.
Multiparameter benchtop meter case
With a timeless, classy design the professional multiparameter benchtop meter's case reflects the top quality rating of the ProLab instruments. Housed
in a solid metal body the multiparameter benchtop meter's big and brilliant graphic display is protected by a one piece glass slide. The
large QVGA brilliant color graphic display provides outstanding legibility minimizing reading errors on the multiparameter benchtop meters. The
multiparameter benchtop meter's powerful luminous display with backlighting is legible from six to nine meters away and at an angle. The
ProLab 4000 multiparameter benchtop meters offer the choice between the full display for pH, mV, or ISE (channel 1 or 2) and a split display for
double pH (mV, ISE) for parallel display of channel 1 and 2. The two input channels are galvanically isolated on the multiparameter benchtop
meter. This isolation allows the multiparameter benchtop meter to simultaneously measure with two pH electrodes even in the same container. The
multiparameter benchtop meter's weight of approximately 5 1/2 pounds (2.5 kg) guarantees a firm base. With an IP 54 rating the multiparameter
benchtop meter electronics are completely sealed against dust and water splashes from all sides. The chemically resistant design also makes
the ProLab multiparameter benchtop meters easy to clean and disinfect. The S4D stand can be attached without tools either to the left or the
right side of the multiparameter benchtop meter to create an immovable unit. The three hinged construction of the multiparameter benchtop
meter's arm was designed for maximum comfort during sample measurement and holding the electrode into the sample beaker.
Multiparameter benchtop meter data functions
The multiparameter benchtop meters calibration protocols comply with GLP requirements. The last ten calibrations along with 10000 date, time, and ID stamped measurement results can be recalled from the multiparameter benchtop meter's memory. The data can be stored on the multiparameter benchtop meters in seven selectable intervals from 1 second to 60 minutes in addition to being able to select the measuring parameters. With a clock rate of 300 MHz the multiparameter benchtop meter can take rapid measurements. Additionally the 32 MB of flash memory and 32 MB of RAM allow for a huge amount of data recordings, however if this is not enough memory a USB stick can be directly connected to the multiparameter benchtop meter to increase the memory capacity. The multiparameter benchtop meters can have different colors assigned to the measuring parameters and have limits set to alarm when certain values are exceeded. All data is stored by the multiparameter benchtop meter according to 21 CFR Part 11 in hierarchy levels with user identification. The ProLab 4000 professional multiparameter benchtop meters have open communication with a large number of interfaces such as USB slave, USB host, and RS 232. The multiparameter benchtop meter can export data in either CSV or XML format. The multiparameter benchtop meters USB host offers connection to devices such as a mouse, PC keyboard, memory stick, USB hard disk, printer, and barcode reader. The multiparameter benchtop meter can communicate to all peripheral devices at the same time by connecting a hub switch to the USB host. No adapters are required to interface the multiparameter benchtop meters to your PC and peripherals such as printers and USB sticks are automatically recognized. Operating the multiparameter benchtop meters is similar to a PC by using a menu bar. Navigation on the multiparameter benchtop meters can be done via either the navigation keys or the included mouse. Text and numbers can be entered directly into the multiparameter benchtop meter's 12 key keypad. All functions can be accessed via the multiparameter benchtop meter's navigation menu similar to Microsoft Windows. The multiparameter benchtop meter's main functions are linked to preset keys. Also, similar to a PC the multiparameter benchtop meter's firmware can be upgraded using free updates posted on our website.
Other multiparameter benchtop meter functions
The multiparameter benchtop meters have an integrated stability control feature which checks the measured value's stability. The measured
value is only released when certain stability criteria is reached by the multiparameter benchtop meter. The criterion is adapted to SI
Analytics electrodes to achieve the best compromise between accuracy and speed of measurement on the multiparameter benchtop meter. This
prevents the multiparameter benchtop meter from making measurement errors due to premature readings of unstable values. The multiparameter
benchtop meter's stability control feature is automatically activated for all sensor calibrations. For measurements the multiparameter
benchtop meters' stability control feature can be switched on or off. The multiparameter benchtop pH meters can also accept ISE measurements
with a measuring range from 1.0E-40 to 9.9E39 mg/l using a 2 to 9 point calibration with standards from 1.00E-30 to 1.00E30 mg/l. The
multiparameter benchtop meters also offer several special ISE functions including standard addition, double standard addition, standard subtraction,
sample addition, sample subtraction, and dummy data addition. Complete IQ and OQ documentation is available for the multiparameter benchtop
meters.
Multiparameter benchtop meter applications
The ProLab 4000 multiparameter benchtop meter is ideally suited for a wide range of applications in chemistry, pharmacy, biotechnology, and food
industry labs.
