These UVP Blak-Ray UV Intensity Meters provide accurate and repeatable readings of either shortwave (220 to 280nm) or longwave (300 to 400nm) ultraviolet light. The meters are self-powered for maximum portability. Each meter features two scales for low and high-intensity readings. A 5X attenuation screen is provided for very high intensity lamp measurements.
A 4-foot cord connects the sensor to the meter for remote readings. Infrared filter ensures accuracy when measuring light sources producing IR radiation. Longwave Meter EF28195 complies with MIL STD 45662-A and can be found in MIL-I-6868D (NSN 6635-488-5451).
