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. |
APPLICATIONS
| Water Treatment Plants |
| Purification Systems |
| Environmental testing |
|
| 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. |
