Pma2122.jpg (8518 bytes)The PMA2122 Germicidal detector provides fast and accurate irradiance measurements of the effective germicidal radiation. Ultraviolet radiation at 253.7nm has been used in germicidal applications for several decades. 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.
