Featuring a horizontally constructed photodetector assembly that keeps the photodetector out of the hot zone, the X1-1-RCH-116-4 UV and blue light LED curing radiometer reportedly is able to maintain stability in high-temperature and intense UV flood and spot curing environments. The fully remote controllable four-channel X1-1 meter features auto-ranging from 0.1 pA to 200 uA or manual range selection, CW, dose, run/stop, offset and peak hold functions, selectable integration time from 20 ms to 1 second, USB interface, and backlit LCD. The unit is reportedly compatible with all other Gigahertz-Optik single- and multi-sensor light detector heads.

The wand-style detector reportedly consists of a RADIN radiation integrator coupled to a stainless steel rigid tube, housing a quartz light guide that pipes the light signal to a detector capsule housing the photosensor/filter assembly. RADIN not only provides a cosine corrected spatial response, but along with the light guide and remote detector capsule, provides signal attenuation and thermal isolation. The detector assembly is not subject to direct irradiation that reduces ageing and saturation effects and allows the RCH detector to operate in temperatures up to 1,000°C, with peaks up to 2,000°C.
