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

• 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 Radiometer is powered by a 9-volt battery for up to 120 hours
• Unit includes a port for attachment of a chart recorder (user provided)

All meters and sensors are individually serialized for traceability of calibration. Calibration is recommended every six months and is certified to meet UVP's published standards and is traceable to NIST. Calibrations are performed at UVP's factory.
