Process Transmittance Monitor (with wiper/auto cal.), 10m (33 ft), cleaning swab

Monitoring UV-Transmittance is an important part of UV system control. The Sensorex UVT-LED (PearlSense T254) is the world's first UVT monitor to incorporate a UV-C LED light-source in place of a conventional mercury lamp. This ensures extremely stable readings in all conditions, over an extended lifetime. The unique design utilizes a single lamp and sensor, eliminating drift seen in designs using multiple lamps and sensors. It can be installed directly into a pipe, an open channel, or used offline. UV-Transmittance is measured automatically and displayed on the backlight LCD screen. With its low operating cost, small footprint, and ultra long lamp life, it's the perfect solution for reliable water testing.
