Измеритель яркости экрана тестер SM208 фотометрия 0 01-39990cd/m2

Features:

           Adopting a detector powered by a silicone photocell with high stability, photostability, 

          and shock resistance, strict vision correction and accurate photometric measurement can be realized. 

           With a wide measuring range, it can measure between 0.01-39990cd/m2 without a dimmer.

           It is a digital display with good indication reproducibility, data latching and peak value latching functions; 

           With very low power consumption, it can operate continuously for 100 hours on a 9V layer-built battery; 

           Mini light probe, measuring angle <100;

           Compact, portable, easy to use.
