J-Series
UV Meters These meters are photovoltaic devices for taking accurate and repeatable readings of UV light sources. Model J-225 measures the intensity of shortwave UV (254nm). Each meter comes with a sensor, attenuation screen and filter. This meter's sensor is sensitive within a range from 220 to 280nm with maximum sensitivity at 254nm. Longwave readings are made with the J-221 Meter. It's sensor is sensitive from 300 to 400nm with a peak sensitivity at 365nm. J-221 Meter complies with MIL STD 45662-A and can be found in MIL-I-6868D (NSN 6635-488-5451). Each meter features two scales for low and high intensity readings. For remote readings, a four foot (1.2m) cord connects the sensor to the meter. Two scales measure a wide range of intensity. An infrared filter assures accurate readings when measuring light sources producing infrared radiation. The 5X attenuation screen can be used for very high intensity lamp measurements. |

The UVX's range switch provides selection from three intensity ranges: 0
to 20 mW/cm2, 0 to 2000 microW/cm2 and 0 to 200 microW/cm2. The chart
recorder port, standard on the UVX, allows for continuous monitoring.
The 10:1 attenuator extends the reading range up to 200mW/cm2. The UVX
Radiometer is powered by a 9-volt battery for up to 120 hours.
