Multi-parameter Meters Product Description
|
The compact precision Multi 3400i Multi-parameter Meters enable you to carry out pH measurements, dissolved oxygen (DO) measurements
and conductivity measurements quickly and reliably. The Multi 3400i Multi-parameter Meters provide the maximum degree of
operating comfort, reliability and measuring certainty for all applications. The multi-parameter meter is hose-proof with
battery or optional AC adapter and is optimally suited for use in the field, in laboratories, or at production sites.
The Multi 3400i Multi-parameter Meters have several useful features including an energy saving feature to avoid unnecessary battery
depletion. The energy saving feature switches the multi-parameter meter off if no key has been pressed for an hour. The
multi-parameter meter can perform pH measurements with or without a temperature sensor or by using the conductivity or oxygen probe's
built in temperature sensor. The multi-parameter meters recognize which sensors are connected and automatically switch to the
correct mode for the temperature measurement. The multi-parameter meter's AutoRead function (drift control) checks the
stability of the measurement signal.
pH/Oxi or pH/Cond Multi-parameter Meters
WTW multi-parameter meters stand for precise multi-parameter measuring technology. The pH/Oxi 3400i multi-parameter meter for
the determination of pH, oxygen and temperature and the pH/Cond 3400i multi-parameter meter for the determination of pH, conductivity
and temperature are favorably-priced alternatives to the single parameter instruments for applications which require the measurement
of several parameters. The multi-parameter meters are hose-proof and also meet the requirements of IP 66. Kits include a
professional case with sample beakers, multi-parameter meter, pH electrode and oxygen or conductivity sensor, STH 320 stand and
calibration and maintenance supplies.
TetraCon® 325 Conductivity Probe
The TetraCon® 4-electrode system sets a new standard for professional conductivity measurements. In comparison with conventional
measuring cells with 2 electrodes, the TetraCon® 325 conductivity cell offers numerous technical advantages:
- Highly accurate and linear because of optimized cell geometry
- Extremely large measuring range with just one cell
- Long-term cell constant stability with high-quality abrasion-resistant graphite electrodes
- Built-in temperature sensor as standard
- Smallest immersion depth possible
- Automatic resistance compensation provides accurate measurements even with a dirty electrode
- Measurement not affected by cable influences, polarization effects or contact with side walls
- Robust, unbreakable epoxy body
