GNST-SD237
Color online sensor
Color online sensorIt 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 measurement. This analyzer usesRS485 interface and standard Modbus protocol, quickly respond to changes in water color.

This analyzer usesRS485 interface and standard Modbus protocol, 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 been unanimously recognized by a large number of users.
productprinciple
Two light sources are used, one for measuring chromaticity and the other for photoelectric measurementA system composed of ji tubes, quartz windows, etc. is used to simulate human eye observation, and an algorithm is used to establish a stable and reliable water quality chromaticity calculation model. Another method 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 solids to a certain extent, thereby achieving stable and reliable measurement..
Product Features
(1) Optical detection, no need for reagents, more economical and environmentally friendly
(2) Equipped with cleaning brush and circulation pool, effectively removing attachments and bubbles from the measurement window, maintenance free
(3) Dual light path detection, automatically deducing interference from turbidity on chromaticity measurement, unaffected by turbidity
(4) Corrosion resistant casing, waterproof rating IP68, RS485 communication interface, standard ModBus protocol for easy integration
