Ultraviolet Germicidal Irradiation (UVGI) for accurate dose measurements

Model PMA2122 Digital Germicidal UVC Sensor (UVGI)

Solar Light’s Model PMA2122 Digital Germicidal UVC Sensor provides fast and accurate dose measurements of the effective Ultraviolet Germicidal Irradiation (UVGI).

Ultraviolet Germicidal Irradiation (UVGI) Guidelines:
PMA 2122: UVC intensity <1500 uW/cm2
PMA 2122G: UVC intensity >1500 uW/cm2



Solar Light’s Model PMA2122 Digital Germicidal UVC Sensor provides fast and accurate dose measurements of the effective Ultraviolet Germicidal Irradiation (UVGI). Ultraviolet radiation at 253.7nm has been used in germicidal applications for several decades. Microorganisms in air and water can be killed using UV or a combination of UV and ozone. The UVC-producing germicidal lamps in purification systems must be continually monitored to ensure that the bacteria are receiving a lethal dose of radiation. When properly monitored, these expensive lamps can be utilized to their maximum useful life before replacement. The PMA2122 sensors can also be used to ensure that replacement lamps are performing to specification. Several packages are available for different types of environments, including standard, low profile, and weatherproof.

  • Water Treatment Plants
  • Purification Systems
  • Environmental testing
