UVP UVX Radiometer

  • Order from three sensors: UVX-25 shortwave, UVX-31 midrange or UVX-36 longwave

  • The chart recorder port, standard on the UVX, allows for continuous monitoring

  • The UVX's range switch provides selection from three intensity ranges:
    0 to 20 mW/cm2, 0 to 200 microW/cm2 and 0 to 2000 microW/cm2

  • The 10:1 attenuator extends the reading range up to 200 mW/cm2

  • The UVX Radiometer is powered by a 9-volt battery for up to 120 hours

Product Details

Three interchangeable sensors

This digital UVP UVX Radiometer is used with one of the three interchangeable sensors (ordered separately) for measuring 254 nm, 302 nm and 365 nm UV wavelengths. Measurement of lamp irradiance is the most effective way to monitor the useful life of any UV light source. Unit includes a port for attachment of a chart recorder (user provided).

Applications include:

  • Quality Control

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 our factory.
