The Germicidal Lamp Monitor is designed to monitor banks of underwater germicidal lamps used in water treatment facilities.

The GLM100 Germicidal Lamp Monitor consists of the LM100 Lamp Monitor and the UW254 Germicidal Detector.

A UV lamp monitor can reduce maintenance costs by determining exactly when germicidal lamps in wastewater treatment plants need to be serviced.  Since most plants have no way to determine when buildup on lamps has reduced their effectiveness, they are typically removed and cleaned at routine intervals that are considerably shorter than necessary. 

The LM100 was specifically designed to monitor output from Solar Light Co.'s UW254 submersible germicidal detector but will accept output from any 4 to 20mA detector (two wire).

The UW-254 is an UV detector designed to monitor up to four mercury lamps with a radiation peak at 253.7 nm that are commonly used in banks for the final disinfection of plant effluent. The probe is "calibrated" after initial installation of the lamp bank and readjusted after cleaning. The LM100 lamp monitor is adjusted to indicate 100% for clean lamps. Then appropriate operator alert levels are set for the specified decrease in intensity.The UW-254 detector has a narrow spectral response from 210-380 nm. It will not respond to sunlight -- or any other visible radiation -- and offers negligible response to the sun's UV radiation -- nil in service underwater.
