Operation Principle
UV254 probe provides in-situ continuous organics monitoring utilizing a 254nm ultraviolet LED source. The amount of light absorbed provides an indication of natural organic matter. It serves as a continuous surrogate measurement for organic carbon (TOC), COD, and SAC. The UV254 probe comes with built in turbidity compensation and LED reference to ensure accurate, stable, and reliable measurements.
Features
l RS-485 output, support MODBUS
l No chemicals, direct UV254 measurement, UV LED technology
l Measurement of SAC、COD、TOC
l Automatic turbidity compensation
