ITT-LP Loop Powered pH/ORP/mV Analyser

The TT-LP pH/ORP/mV Analyser is a reliable and affordable isolated 2-wire loop powered microprocessor-based analyser that is designed to be sturdy and user-friendly. It is capable of measuring pH, mV and temperature with large LCD display. It is assembled in a watertight 1/4 DIN case, and designed for laboratories and process control applications.

The output of TT-LP pH/ORP/mV Analyser is via the 2-wire DC power supply loop with input / output isolation to eliminate ground loops and ground voltage difference. Both the 4mA and 20mA output can be assigned to specific pH or ORP (mV) values, for a more refined output.  pH value is affected by temperature. You can select ATC (automatic temperature compensate) or MAN (manual temperature compensate) to compensate pH value. The TT-LP pH/ORP/mV accepts 2 buffer sets (pH 4.01, 7.00, 10.01) or (pH 4.00, 6.86, 9.18) for pH calibration, and supports either 1 or 2 points pH calibration.

The analyser has a wide operation voltage range from 12V to 36V DC and support other features including electrode offset recognition, electrode slope recognition, electrode efficiency display, built in buffer coefficients, and auto-saving pH calibration values and setting parameters.
