UviTec UV254 Sensor

The UviTec UV254 bypass sensor provides affordable real-time measurement of organic matter in water or wastewater. The UV254 sensor utilizes light at the 254 nm and 550 nm wavelengths for organics monitoring. Designed to meet the needs of many monitoring applications, it offers multiple flow cell designs and sensor path length selections for the desired measurement range.

Features & Benefits

Affordable real-time UV254 organics monitoring
Dual wavelength sensor (254 nm and 550 nm)
Wastewater to high purity measurement ranges
Bypass style sensor with multiple flow cell selections to meet application demands
Operator friendly, low maintenance design
Reagent free optical measurements
Simple to install and operate

Simple, Plug & Play UV254 Monitoring

The UviTec UV254 bypass sensor is a cabinet style instrument installed directly on a wall, railing or system backboard. Sample is supplied to the sensor from a pressurized source or alternatively, from an open-channel using an accessory pumping/cleaning system. The sensor must be connected to a UviTec controller for operation.

EXAMPLE CONFIGURATION

UviTec Controller
For affordable, user friendly operation and control
UviTec UV254 Bypass Sensor
For real-time continuous UV254 organics measurement
UviTec Clean System
For low maintenance automatic cleaning

Multiple sensors can be added to UviTec's controllers to expand water quality monitoring capabilities.

Simple to install, easy to operate, no reagents and no waiting for lab results.
