Hand-held radiometer is a state-of-the-art measuring device ideal for obtaining accurate and repeatable UV irradiance measurements. Built to withstand day-to-day use in laboratory and production environments.

Compact, portable, easy-to-operate unit features automatic self-test circuitry, read/hold switch, low battery indicator, and a 9.1 cm (3¹⁹/₃₂") window with LCD readout

Port enables unit to be connected to a chart recorder for continuous monitoring. Unit operates for 120 hours on a 9 V battery (not included).

Unit accommodates three interchangeable sensor probes (sold separately) sensitive in the 254 nm, 365 nm, and 302 nm regions of the ultraviolet spectrum. Probes feature 0.9 m (3') electrically shielded cables and are capable of measuring sensitivity ranges from 0 to 20 mW/cm², 0 to 2000 µW/cm², and 0 to 200 µW/cm². A 10:1 attenuator screen accessory (sold separately) extends UV measurement range to 200 µW/cm².
