Description
Overview
GAOTek water quality sensor is designed and made based on the principle of scattered light based measurement of suspended matters. When a beam of light shots into the water sample, it will be scattered by the suspended substance in the water sample. by measuring the intensity of backward scattered light and comparing it with the internal calibration value, the suspended substance in the water sample is calculated, and the final value is output after linearized Â
Features
- Based on scattered light principle, with built in temperature sensor
- Supportive of RS 485, Modbus or RTU protocol
- Optical fibber structure, strong ability to resist external light interference
- Infrared LED light source, and high stability
- IP68 protection, within the water depth of 20 meters
