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 8 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.
