UVP J-Series Photovoltaic UV Intensity Meters: Model J-221

• With two scales for low and high intensity readings
• Measures the intensity of longwave UV (365nm). The sensor is sensitive from 300 to 400nm with a peak sensitivity at 365nm
• 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 5× attenuation screen can be used for very high intensity lamp measurements
• Meters are self-powered for maximum portability

All meters and sensors are individually serialized for traceability of calibration. Calibration is recommended every six months and is certified to meet UVP's published standards and is traceable to NIST. Calibrations are performed at UVP's factory.
