J-225 254 nm Shortwave Meter
Description
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.

Frequently Asked Questions
Can the J-225 254 nm Shortwave Meter be used to measure lamps with different spectral distributions?
If a meter is calibrated to provide correct readings with a particular lamp, it will not provide correct values for lamps with different spectral distributions. However, relative comparisons of lamps with identical spectral distributions of UV light can be made with any stable meter, regardless of the calibration method used, as long as the meter has sensitivity in the desired wavelength region.
Calibration is recommended every six months for the J-225 254 nm Shortwave Meter.
For best accuracy, the J-225 254 nm Shortwave Meter should be re-certified every six months.
The J-225 254 nm Shortwave Meter is used for taking accurate and repeatable readings of UV light sources in either the 365 nm or 254 nm UV range.
The significance of meter readings for the J-225 254 nm Shortwave Meter depends on several considerations, including the absolute spectral response of the meter, the spectral output of the emitter, and the spatial response of the meter.
