J-Series Ultraviolet Meters

The J-Series UV meters are photovoltaic devices for taking accurate and repeatable readings of UV light sources in either the 365nm or 254nm UV range.

J-Series Meters


  • Quality Control


Main Features

  • J-225 Meter measures the intensity of shortwave UV (254nm). Each meter comes with a sensor, attenuation screen and filter. This meter's sensor is sensitive within a range from 220 to 280nm with maximum sensitivity at 254nm
  • J-221 Meter measures the intensity of longwave UV (365nm). The sensor is sensitive from 300 to 400nm with a peak sensitivity at 365nm. J-221 Meter complies with MIL STD 45662-A and can be found in MIL-I-6868D (NSN 6635-488-5451)
  • Each meter features two scales for low and high intensity readings
  • For remote readings, a four foot (1.2m) cord connects the sensor to the meter
  • Two scales measure a wide range of intensity
  • An infrared filter assures accurate readings when measuring light sources producing infrared radiation
  • The 5X attenuation screen can be used for very high intensity lamp measurements
  • Meters are self-powered for maximum portability
