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.
