SM208 Digital Screen Brightness Meter LED Display Lightness Tester

I.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 <10O;

Compact, portable, easy to use
