pH and Temperature Sensing RS485 Transmitter Module - Temperature Sensor Included

The pH and Temperature Sensing RS485 Transmitter Module (pH Sensor + Temperature Sensor Included) is a transmitter module featuring an RS485 Modbus RTU output, designed for the simultaneous measurement of pH and temperature values ​​in liquids.

Thanks to the RS485 output, pH and temperature data can be digitally transmitted to devices such as PLCs, HMIs, industrial controllers, data logging systems, or microcontrollers supporting RS485. The RS485 output supports Modbus RTU communication.
