Measurement of lamp irradiance is the most effective way to monitor the useful life of any UV light source. The UVX Radiometer is used with one of the three interchangeable sensors (purchased separately) for measuring 254nm, 302nm or 365nm ultraviolet wavelengths. All sensors are calibrated with traceability to the National Institute of Standards and Technology (NIST). Accuracy of sensors is +/-5%. Cable length of each sensor is three feet for measuring UV in remote locations.
Measure in three intensity ranges: 0 to 20 mW/cm2, 0 to 2000 uW/cm2, and 0 to 200 uW/cm2. A port for access to a chart recorder (not included) allows for continuous monitoring. An optional 10:1 attenuator extends the reading range up to 200mW/cm2.
Radiometer operates with 9-volt battery (available separately) for up to 120 hours. Recalibration of the sensors is recommended every six months.
Dimensions: 6.2L x 2H x 3.6W in. (157 s 51 x 91mm). Sensor cable length of 3 feet (0.9m).
