Multi-parameterMeters Product Description
The compact precision Multi 3400i Multi-parameterMeters enable you to carry out pH measurements, dissolved oxygen (DO)measurements and conductivity measurements quickly and reliably.ÿ The Multi3400i Multi-parameter Meters provide the maximum degree of operating comfort,reliability and measuring certainty for all applications.ÿ Themulti-parameter meter is hose-proof with battery or optional AC adapter and isoptimally suited for use in the field, in laboratories, or at production sites.
The Multi 3400i Multi-parameter Meters haveseveral useful features including an energy saving feature to avoid unnecessarybattery depletion.ÿ The energy saving feature switches the multi-parametermeter off if no key has been pressed for an hour.ÿ The multi-parametermeter can perform pH measurements with or without a temperature sensor or byusing the conductivity or oxygen probe’s built in temperature sensor.ÿ Themulti-parameter meters recognize which sensors are connected and automaticallyswitch to the correct mode for the temperature measurement.ÿ Themulti-parameter meter’s AutoRead function (drift control) checks the stabilityof the measurement signal.
pH/Oxi or pH/Cond Multi-parameter Meters
WTW multi-parameter meters stand for precise multi-parameter measuringtechnology.ÿ The pH/Oxi 3400i multi-parameter meter for the determinationof pH, oxygen and temperature and the pH/Cond 3400i multi-parameter meter forthe determination of pH, conductivity and temperature are favorably-pricedalternatives to the single parameter instruments for applications which requirethe measurement of several parameters.ÿ The multi-parameter meters arehose-proof and also meet the requirements of IP 66.ÿ Kits include aprofessional case with sample beakers, multi-parameter meter, pH electrode andoxygen or conductivity sensor, STH 320 stand and calibration and maintenancesupplies.
TetraCon?325 Conductivity Probe
The TetraCon? 4-electrode system sets a new standard for professionalconductivity measurements.ÿ In comparison with conventional measuring cellswith 2 electrodes, the TetraCon? 325 conductivity cell offers numeroustechnical 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
