Product Description
AnalytikJena's J-Series UV meters are photovoltaic devices for taking accurate and repeatable readings of UV light sources in either the 365nm or 254nm UV range. The measurement of lamp irradiance is the most effective way to monitor the useful life of any UV light source, and use of these meters will help ensure maximum operating efficiency of UV light sources. The durable, plastic housings of the UV meters are impact-resistant and can withstand heavy, sustained use. Individually serialized for traceability of calibration. Calibration is recommended every six months and is certified to meet AnalytikJena 's published standards and is traceable to NIST.
Features
- 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,
- Meters are photovoltaic self-powered for maximum portability.
