High-Precision Industrial Digital Rs485 PH Sensor for Water Quality Monitoring

Short Description:

The pH Sensor employs an isolated power supply design to ensure stable performance and robust anti-interference capabilities. Ideal for water quality monitoring, industrial processes, and laboratory applications, it supports automatic/manual temperature compensation and multiple calibration solutions (USA/NIST/custom). Featuring a flat bubble structure for easy cleaning and a ceramic sand core liquid junction for reliable measurements, this sensor delivers high accuracy (±0.02pH) across a 0-14pH range. Its compact, polymer plastic housing and RS-485 MODBUS output make it durable and easy to integrate into diverse systems, even in harsh environments.
