The J-Series UV intensity Meter is a photovoltaic device for measuring the intensity of UV light sources. This unit is ideal for monitoring germicidal lamp irradiance, measuring Q.C. inspection lamps, and producing accurate and repeatable measurements for critical experiments. All J-Series Meters are certified to be within UVP’s published standards and traceable to the National Bureau of Standards.
Long wave intensity readings are made with the J-221. The long wave sensor is sensitive from 300 to 400nm with a peak sensitivity at 365nm.
The J-221 is specified for many government applications and complies with government standards MIL-I-6868D and NSN-6635-488-5451.
Each unit features plug-in type sensors and two scales for low and high intensity readings. For remote readings, a 4ft (1.22m) extension cord connects the sensor to the meter. To ensure accurate measurements, an IR filter is included for measuring lamps which produce infrared radiation. Also, a reduction screen can be used to attenuate the UV for very high intensity lamp measurements.
Designed for ease of use operation, the J-Series UV Meter provides a reliable method for monitoring UV light source efficiency.
