About this product

A handheld meter with a corded probe that measures UVA/UVB irradiance over roughly 280-400 nm (calibrated at 365 nm), spanning 1 uW/cm2 up to 40 mW/cm2, used to check long- and medium-wave UV sources in applications like forensics, chromatography and dermatology. A backlit display shows the live reading while a secondary readout tracks minimum, maximum, average and recorded values, and it can log up to 20 timed data points. Rated accuracy is about +/-4% plus one digit, and the separate probe with tripod and magnetic mounting lets you position the sensor precisely at the measurement point.
