KWS-500 Online ORP Sensor with Analog Output

Introduction

KWS-500 online ORP sensor uses long-life industrial online electrodes and built-in temperature sensor for automatic temperature compensation, suitable for long-term online monitoring. The sensor uses RS485 communication interface and standard Modbus protocol, which can be easily networked and integrated without a controller. It is widely used in water quality treatment, hydrological monitoring, wastewater treatment, swimming pools, industrial control, biology and other 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.
