UVSense Online UV254 Analyzer

Product Details

Online UV254 Analyzer

The UVSense Online UV254 Analyzer of Bebur Company adopts the principle of ultraviolet-visible light spectroscopy and can measure the components of organic matter in water, mainly including TOC, BOD, COD, NO3-N, DOC, etc. The sensor is equipped with turbidity compensation function, which can improve the measurement accuracy during actual measurement. It is applicable to online monitoring of waterworks, reclaimed water treatment, domestic sewage, industrial wastewater and natural water bodies.

UVSense Online UV254 Analyzer

Typical applications

▪Waterworks

▪Effluent monitoring of sewage treatment plants

▪Monitoring of river basins, surface water and groundwater

▪Urban domestic sewage treatment plant

▪Monitoring of water treatment in industry

Performance characteristics

▪Dual-wavelength, multi-wavelength or full-spectrum measurement is adopted

▪Optical in-situ measurement, no chemical reagents required

▪Fast measurement, with the fastest measurement cycle being 10 seconds

▪The maintenance-free period is long, and the sensor comes with a built-in cleaning function

▪RS485 communication

▪IP68 protection grade

▪It can be used as a substitute for the measurement of TOC, COD, BOD and NO3-N
