KWS-500 ORP Probe – ORP Sensor for Pool Monitoring
Introduction
Kacise applies 4-electrode couple measure tech sensor to make the sensor has better repeatability and stability, not susceptible to ambient.
The orp probe’s automatic cleaning brush effectively eliminates ar bubbles and reduces the effects of contamination on the measurement.
Long-term online use, longer maintenance intervals and better stability.
Feature
- Digital sensor, RS-485 output, support MODBUS
- Strong anti-interference ability, no ambient light and chromaticity
- Multi electrode couple measure technology repeat-ability.
Dimensions

Kacise is happy to explore the sensor world with you, focusing on optical detection, capacitance detection, ultrasonic detection, electromagnetic detection, electrochemical detection principles. We hope to use our technical advantages to help solve your problems and improve your feelings.
