> Detectors need to be used with a Radiometer

> Analog version of this detector can be used with any 0 to 5 VDC or 4 to 20mA recording device

Microorganisms (bacteria) ,usually in air or water, can be killed using UV or a combination of UV and ozone. The UV producing lamps in the purification systems must be monitored to insure that the bacteria are receiving a lethal dose of germicidal radiation. The expensive UV lamps can be monitored to get maximum life out of the lamp before replacement. The germicidal detector can also be used to insure that the proper lamp has been installed after replacement.
