KWS-500 Online ORP Digital Sensor

Introduction

The KWS-500 online ORP sensor features long-life industrial online electrodes and a built-in temperature sensor for automatic temperature compensation, fitting long-term online monitoring. With an RS485 communication interface and the standard Modbus protocol, it can be easily networked and integrated without a controller, and is widely applied in water quality treatment, hydrological monitoring, wastewater treatment, swimming pools, industrial control, and biology fields.

Feature   

• Digital sensor, RS-485 output, standard MODBUS protocol;
• No electrolyte required, strong anti-interference, no need for frequent calibration;
• Built-in temperature sensor, automatic temperature compensation;
• Adopt high-performance industrial online electrode, can work stably for a long time;
• Built-in calibration parameters, accurately calibrated at the factory, can be directly installed and used.
