Details:
Screen Brightness Tester /Screem illuminometer /intensity of illumination
Item:SM208
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
