pH and Temperature Sensing RS485 Transmitter Module - Includes pH Sensor + Temperature Sensor

pH and Temperature Sensing RS485 Transmitter Module - Includes pH Sensor + Temperature Sensor

The pH and Temperature Sensing RS485 Transmitter Module—which includes both pH and temperature sensors—is a transmitter module featuring an RS485 Modbus RTU output, designed for the simultaneous measurement of pH and temperature levels in liquids.

Thanks to its RS485 output, pH and temperature data can be digitally transmitted to devices such as PLCs, HMIs, industrial controllers, data logging systems, or microcontrollers that support RS485 communication.
