Accumulated UV Meter / Digital UV Intensity Meter UIT Accumulated UV Meter / Digital UV Intensity Meter 06
UIT SERIES UIT-250 Accumulated UV Meter Features Allows measurement of the temperatures, or five wavelength ranges (with central wavelengths of 172 nm, 254 nm, 313 nm, 365 nm, and 405 nm) by simply replacing the detector unit. Switching functions: UIT can select power source by AAA battery x 3 or external (AC Adapter: option) Compatible with Extension Cables (main unit ~ photoreceptor: 2m as standard option) Versatile enough to measure irradiance, peak irradiance, accumulated light amount, irradiance distribution,spot-light irradiance, and temperature distribution. Built-in memory allows measurement of irradiance distribution for up to 4 minutes. Effective / Invalid Change of an Auto Power-Off Function PC Serial Communication Functions Reading of Irradiance Distribution Data Confirmation of Sample/sec Switching of Measurement Range Measurement of Irradiance (Temperature) Configuration UIT-250A can use AAA battery or AC adapter AC100V/For Japan Use Only.
