PH Meter

PH Sensor

FREHNIG pH transmitter is an easy to use instrument with all the necessary tools for online measurement and monitoring of pH. The FDP 2021 features high impedance analog front end with high resolution Analog to digital conversion for superior performance. The FDP 2021 transmitter accepts any 2 wire single junction pH electrode and a PT-100 probe for temperature measurement. The 2 line alphanumeric display shows both pH & temperature measurements. The transmitter has 3 point calibration for linear measurement. Temperature sensor can also be calibrated for span & zero. Automatic temperature compensation can be enabled/disabled using the menu. Manual temperature compensation is also programmable. The 4-20 mA outputs are again of high resolution and can be scaled digitally. The 485-communication is done over MODBUS protocol for easy implementation of DAQThe FDP 2021 transmitter accepts a two wire TDS sensor with a cell constant from 0.1 to 10 The 2 line alphanumeric display shows TDS in ppm The transmitter has 3 point calibration for linear measurement. The 4-20 mA outputs are again of high resolution and can be scaled digitally. The 485-communication is done over MODBUS protocol for easy implementation of DAQ.
