SPS-M-Lxx Multi-Wavelength Spectrum Water Quality Sensor
Based on the ultraviolet absorption spectrum principle, the multi-wavelength spectrum water quality sensor can measure organic matter and nitrate nitrogen in water and has a turbidity compensation function, effectively improving the accuracy of actual water samples. It is suitable for monitoring domestic, industrial, and watersheds. Compared with conventional chemical detection, it has the characteristics of high reliability, zero pollution, and zero delay and can realize real-time online monitoring of organic pollutants.
The SPS-M Multi-wavelength Spectrum Water Quality Sensor can be matched with our MC series data collector and cloud service to realize remote real-time data monitoring and remote equipment operation and maintenance.
Parameter: COD, TUR, Nitrate, TOC, BOD, UV254, Temperature
- Using four wavelengths to measure, obtaining more spectral information on water samples
- Optical in-situ measurement, no chemical reagent consumption, environmentally friendly
- Quick measurement: the shortest measurement cycle is 1 second
- The maintenance-free period is long, and the sensor has a cleaning brush.
- RS485 communication mode can quickly connect to the meter.
- IP68 protection grade can be used in harsh environments.
- It has low power consumption, can be powered by a battery, and is convenient for equipment deployment.
