UW254 Underwater Germicidal Detector
Solar Light’s Model UW254 Underwater Germicidal Lamp Monitor is specifically designed to continuously monitor UV intensity from UVC lamps in waste water treatment plants. The sensor provides an indication of the effectiveness of the lamps as they age because it is sensitive to the sterilizing UVC wavelengths of mercury lamps at 253.7nm. The sensor reliably interfaces with the Solar Light GLM100 germicidal lamp monitor, or your choice of monitor or data acquisition equipment.

The sensor reliably interfaces with the Solar Light GLM100 germicidal lamp monitor, or your choice of monitor or data acquisition equipment. Its output is a standard 4-20 mA. The sensor is submersible and can monitor up to 4 lamps by strapping it to a quartz light tube underwater. The UW254 underwater germicidal sensor has a narrow spectral response from 210-380nm. It will not respond to sunlight or any other visible radiation.
UV water disinfection systems are only as good as the effectiveness of the germicidal lamps. With time, even the best UV water treatment system will show a significant degradation in its ability to disinfect water. Germicidal lamp output decreases as the lamp ages and/or becomes dirty through use.
