Features:
1.Powerful measurement functions:it can measure not only current values,naximums,and minimums of illuminance and temperature,but also illuinance difference,integrating illuminance,and average integrating illuminance.
2.Support for automaitic storage of illuminance data (up to 1900 groups) and manual storage of illuminance data(up to 60 groups)
3.Wide measuring range(0 to 200,000lux) and support of automatic range shift
4.Delivered with computer-based analysis software,allowing users to operate the meter with easy
5.Quick response,high portable and operable by a single Handheld
6.The sensor can be rotated
7.backlight
