UVP J-Series Ultraviolet Meters

  • Each meter features two scales for low and high intensity readings

  • For remote readings, a four foot (1.2 m) 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

Product Details

Three interchangeable sensors

The UVP J-Series UV meters are photovoltaic devices for taking accurate and repeatable readings of UV light sources in either the 365 nm or 254 nm UV range. All meters and sensors are individually serialized for traceability of calibration. Calibration is recommended every six months and is certified to meet published standards and is traceable to NIST. Calibrations are performed at Analytik Jena US West's factory.

Applications include:

  • Quality Control
