GNST-SD237 online chromaticity sensor

GNST-SD237 online chromaticity sensor

The chromaticity online sensor is a dual beam probe type intelligent sensor that effectively reduces turbidity interference through automatic compensation. It comes with a cleaning brush to avoid the influence of attachments and bubbles on the measurement. The analyzer adopts RS485 interface and standard Modbus protocol to quickly respond to changes in water color.

Application field

The instrument is widely used in industries such as environmental surface water, sewage treatment, drinking water, swimming pools, etc. and has received high praise from a large number of users.

GNST-SD237 online chromaticity sensorProduct Principle

Using two light sources, one is used to measure chromaticity, and a system composed of light sources, photoelectric diodes, quartz windows, etc. is used to simulate human observation. An algorithm is used to establish a stable and reliable water quality chromaticity calculation model. The other is used to measure water turbidity, and a specific algorithm is used to compensate for the attenuation of the light path and eliminate the interference of particulate suspended matter to a certain extent, thereby achieving stable and reliable measurement.
