Screen Brightness Meter

Model:  SM208

Shenzhen Sanpo Instrument Co.,Ltd     (A1)

 

The SM-208 screen brightness meter is specifically designed to measure the brightness of various fluorescent screens and transmission screens. It has wide applications in the measurement of TV sets, medical X-rays, CRTs and FED and fluorescent substances.

 

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.
