Color Screen Brightness Meter
Model:SM218
Features:
1. Adopting a detector powered by a silicone photocell with high stability, photo stability, and shock resistance, strict vision correction and accurate photometric measurement can be realized.
2. With a wide measuring range, it can measure between 0.01-39990cd/m2 without a dimmer.
3. It is a digital display with good indication repeatability, data hold and peak hold functions;
4. With very low power consumption, it can operate continuously for 100 hours on a 9V layer-built battery;
5. Mini light probe, measuring angle <10O;
6.Compact, portable, easy to use.
