The UVT-LED-H handheld ultraviolet (UV) transmittance monitor (photo) delivers UV transmittance readings in applications employing UV disinfection, and its compact size makes it also well-suited for field measurements, laboratory use and calibration verification of online analyzers. The UVT-LED-H is said to be the only handheld, portable UV-transmittance monitor that is currently available. The device verifies UV dosing and efficient operation of UV disinfection systems in municipal drinking water, wastewater and other industrial water-quality applications, such as food-and-beverage process water, as well as in quality-testing laboratories associated with those applications. The instrument’s highly efficient UV-C LED lamps are more stable, improving accuracy when compared to instruments with traditional mercury light sources, says the manufacturer. Furthermore, the mercury-free light source also significantly lowers operating expenses related to UV transmittance monitoring by eliminating field-serviceable parts and disposal of lamps containing mercury. — Sensorex, Garden Grove, Calif.
