pH/ORP microprocessor transmitter, 4-20 mA-RS485 – Modbus
This transmitter is powered by 9-36 dc volts and provides an isolated 4-20 mA “current loop”, an RS485 and Modbus (function 03) output.

The instrument works with pH/ORP and RTD-Pt100 temperature sensors.
If a Pt100 sensor is connected, the temperature is automatically compensated. The temperature coefficient and reference temperature are adjustable by the user and the temperature is shown in the display.
Its modularity, small size and built-in technology make this transmitter very suitable for measurements the pH/ORP in various processes.
