RK500-09 Multi-parameter water quality sensor

PRODUCT DESCRIPTION

RK500-09 multi-parameter water quality sensor adopts an integrated design and can measure up to 7 parameters at the same time. You can choose DO, COD, pH, ORP, EC/salinity, NH4+, turbidity, etc. Using RS-485 output, Modbus-RTU communication protocol, data can be directly transmitted to the acquisition platform.

The multi-parameter water quality sensor is equipped with an automatic cleaning device, automatic cleaning interval time and number of automatic cleaning cycles can be set to adapt to the water quality of different degrees of cleanliness. The automatic cleaning device can effectively clean the surface of the sensor, prevent the adhesion of microorganisms, and greatly reduce the maintenance cost. Each sensor is equipped with a quick-plug waterproof connector, which is easy to disassemble and assemble.

The sensor protection cover at the front is used to protect the internal sensor from damage. There are slots around the protection cover, which can effectively prevent large suspended particles and biological damage to the sensor probe, while not affecting the accuracy of measurement.

Why Choose the RK500-09? 

• All-in-One Integration: Replace scattered probes with a single water parameter sensor powerhouse.
• Weather-Resistant Design: Built for outdoor extremes—rain, humidity, or temperature swings.
•  Scalable Insights: From single-point checks to ecosystem-wide monitoring.

If you are looking for professional sensors to measure water quality, it will be the great choice.
