Industrial Water pH & Temperature Transmitter – 0–5V / 0–10V / 4–20mA / RS485

This industrial pH and temperature transmitter is designed for reliable, continuous monitoring of liquid pH and temperature in demanding industrial and environmental applications. It uses a high-impedance, three-electrode measurement system combined with automatic temperature compensation, ensuring stable and accurate readings even in harsh or variable water conditions.

The transmitter supports multiple industry-standard outputs including 0–5V, 0–10V, 4–20mA, and RS485 (Modbus RTU), allowing seamless integration with PLCs, SCADA systems, data loggers, and industrial controllers. A one-key online calibration function simplifies routine maintenance, while built-in alarms detect electrode condition and connection status.

Designed for panel or field installation, the compact transmitter offers long service life, fast response, and robust electrical protection for dependable long-term operation.
