Ultraviolet Disinfection System Monitor
UV water disinfection systems are only as good as the effectiveness of the germicidal UV lamps. With time, even the best Germicidal UV water treatment system will show a significant degradation in it's ability to disinfect water. Germicidal lamp output decreases as the lamp ages and /or becomes dirty through use.

The GLM10 screws into the service port of an exposure chamber, where the built-in Germicidal UV sensing probe monitors the lamp.

Designed to display 0 - 100% intensity values, the GLM10 is easily calibrated to 100% when a new lamp is installed. As the lamp ages and the output drops, the display accurately shows the intensity level as a percentage of initial lamp intensity.

A preset threshold is used to determine when the threshold is reached, both the fault light and internal relay are activated for automatic valve control or remote alarm, ensuring a continuous supply of safe drinking water.
