The UVT-LED-PW has been discontinued. While the optical measurement technology in the UVT-LED-PW is the same as in the UVT-LED-H and UVT-LED-SW, we have found that UVT-LED-SW offers more reliable field performance due to its rugged external housing.
Going forward, Sensorex recommends installing our UVT-LED-SW Online UV Transmittance Monitor in all continuous monitoring applications. The UVT-LED-SW can be installed inline or submersed in a tank or open channel. If a local display of UVT values is required, we recommend adding our LPM100 Loop Powered Display, which displays values from any 4-20mA output sensor.
