This radiometer is used to monitor the useful life of any UV light source by measuring lamp irradiance. It operates with a 9 V battery for up to 120 hours. Select three intensity ranges: 0 to 20 mW/cm², 0 to 2000 µW/cm², and 0 to 200 µW/cm². Optional 10:1 attenuator extends the reading range up to 200 mW/cm².
Choose one of the three interchangeable sensors for measuring 254 nm, 302 nm, or 365 nm ultraviolet wavelengths (sold separately). All sensors are calibrated with NIST traceability, and are ±5% accurate. Sensors must be purchased separately. The 3-ft cable length is ideal for measuring UV in remote locations.
