Display

Simultaneous display of conduc-tivity/resistance /salinity and tem-perature; large unit symbols. Icons provide operating instruc-tions and signal unusual operat-ing states. Status indicators pro-vide information on the currentoperating status. Eye-catchingalarm signaling by red, flashingLED.

Calibration

Simple adaptation of the sensorby direct input of the cell con-stant or through manual deter-mination of the constant with a calibration solution.

Sensocheck® sensormonitoring

Reliability due to continual moni-toring of polarization and cableinfluences, indication and alarmtriggering.

HART® communication

Integration in fully automaticprocess cycles is possible due tothe remote control function viaHART® communication. The de-vice can also be fully configuredvia a handheld terminal or fromthe control room. Measured val-ues, messages and device identi-fication can be downloaded atany time.

Also available for hazardous area applications.

Measurement of lowest to high conductivity with 2 or 4-electrode sensors.Exact measurement of ultrapureand natural waters throughspecial temperature compensa-tion. Limit contacts report inad-missible exceeding of conductivi-ty values according to monitorwater quality in the pharma-ceutical industry.
