The DM-series radiometers are offered as separate units to measure light sources in the short wave, long wave and solar UV ranges. Direct intensity readings provided in µW/cm2 over a range of 10 µW/cm2 up to 199,990 µW/cm2 (depending on H or X
versions) — more than ample for high intensity UV sources. The red LED display is equally accurate in dark environment or under ambient light conditions. The housing protects the sensor cell from shock and isolates the photo detectors from thermal gradients during handling, ensuring drift-free measurements. Coiled sensor cord is conveniently stored in readout unit.
