Ultraviolet UV Meter à¤Ã×èͧÇÑ´áʧÂÙÇÕ 850009 Light Meter - Measures Ultraviolet Light UV UV LIGHT METERS 850009 and 850010 • Measure damaging UV (ultraviolet) light in the environment and museums. • UV degradation studies in the pharmaceutical, cosmetic, semiconductor, printing, window tinting, and other industries. • Laboratory chromatography, electrophoresis and forensics. • Test UV sterilization and dermatology lamps in hospitals. UV light intensity appears on the large backlit display in either µW or mW/cm² while the small lower display simultaneously shows minimum, maximum, average and recorded data. Up to 20 data points can be recorded automatically at a variety of intervals. Features zero point reset, hold, and indicates when the battery is low. Comes in a protective hard foam lined carrying case complete with a UV probe, tripod screw, magnetic mount and a 9V battery. Model 850010 measures short wave UV-C light for applications such as UV light fume hoods, UV sterilization, industrial glass and non-destructive testing. Model 850009 measures long and medium wave UV-A/B for applications such as forensics, chromatography, electrophoresis and dermatology. Weight: 4.4 oz (135 g). Dim: 6” x 2” x 1½” (145 x 55 x 40 mm).
