Multiparameter Water Quality Meter Product Description
|
Multiparameter Water Quality Meter
|
The U-50 multiparameter water quality meter brings laboratory accuracy and the ease of push-button operation to water quality
measurement in the field. Eleven parameters can be measured: pH, pH(mV), ORP, temperature, dissolved oxygen, electrolytic
conductivity, turbidity, total dissolved solids, salinity, seawater specific gravity, and depth. Featuring a powerful sensor
probe and state-of-the-art functions, the multiparameter water quality meter makes it easy to get highly reliable water quality
data simply and quickly just by submersing the sensor in the water. The multiparameter water quality meter's control
unit has a waterproof design that allows you to work without concern of splashing or accidentally dropping the instrument in the
water. The multiparemeter water quality meter is flexible enough to use for checking the quality of a broad range of water
samples, from factory effluent to urban drainage, river water, lake and marsh water, aquatic culture tanks, agricultural water
supplies, and sea water. NOTE: Seawater or high salinity water may errode metallic parts. After use, promptly wash the
sensor probe thoroughly with tap water.
Water Quality Meter Control Unit
The U-50 multiparameter water quality meters control unit allows for convenient operation with one hand. The easy to read LCD
screen can display all 11 measurement parameters as the same time. You can change the text size on the multiparameter water
quality meters for easier reading. The multiparameter water quality meters have a patented auto-calibration feature that
provides hassle free calibration. The multiparameter water quality meter's shock resistant cover was designed for rough
treatment in the field and easy cleaning. The U-50 allows the cable to be quickly connected and disconnected to the
multiparameter water quality meter's control unit. The backlit display allows you to even take multiparameter water quality
measurements in the dark.
Water Quality Meter Sensor Probe
The U-50 multiparameter water quality meters have a rugged sensor housing that contain five sensors which provide eleven different
parameter measurements. The turbidity sensor precision has been improved over conventional instruments and the U-53
multiparameter water quality meter has a high precision field replaceable turbidity sensor with wiper. The dissolved oxygen
sensor has improved stability with the multiparameter water quality meters using a new three electrode design for fast response and
polarographic sensor for ease of maintenance. The U-50 multiparameter water quality meters have individually replaceable pH and
ORP electrodes to reduce replacement costs.
Limited Data Logger
The U-50 multiparameter water quality meters can store up to 10000 data sets in memory. Data can be stored manually or
automatically for later display and print out from the multiparameter water quality meter. There is no need to manually record
measured values on site with the U-50 multiparameter water quality meter. Once the multiparameter water quality meter has
recorded data you can recall data for a specific site, a specified date/time, or all of the data depending on your needs. You
can check the multiparameter water quality meter's data capacity at any time by using the data memory check feature. With the
optional USB cable the multiparameter water quality meter's data can be transferred to a computer for further analysis.
The standard handheld multi-parameter water quality measurment system comes with:
- Handheld multiparameter water quality meter with water quality probe and cable
- Instruction manual
- 500 ml pH 4 Buffer
- 250 ml Reference inner solution
- Calibration beaker

Note:
* Battery life based on continuous operation using alkaline C dry batteries when the monitor temperature is over 20°C and the
backlight OFF
* Accuracy is measured by calibrating 4 points for turbidity and electrical conductivity and 2 points for all other measurements
against standard solution.
* Repeatability is measured by the ability to reproduce the results against the standard solution (at 25°C normal pressure
condition).
