pH/ORP microprocessor transmitter, 4-20 mA – RS485 – Modbus

This transmitter powered with a dc voltage between 9 and 36 volt provides an isolated 4-20 mA “current loop”, a RS485 and Modbus (function 03) outputs.

The instrument uses a pH/ORP sensor and RTD Pt100 temperature sensors.
If the Pt100 is connected the transmitter makes automatic temperature compensation (pH only).
In these conditions it is possible to visualise the temperature readout on the display.

Its modularity, small dimensions and built-in technology make it suitable for measurements of pH/ORP in various process applications.
