Product Description

The screen luminance meter is specially designed for measuring the luminance of various fluorescent screens, CRT displays, monochrome 
ransmission screens, color transmission screens, monochrome backlit LCD screens, LCD backlights, mobile color LCD screens, color computer 
TV screens and security indicating screens. It is also designed for a wide range of applications in medical X-ray, electroluminescence 
and other measurement fields.

Product features
1. Using a silicon photocell detector with good stability, light resistance and impact resistance, accurate luminance measurement with rigorous visual 
correction.
2. Wide measurement range, can measure the luminance from 0.01 cd/m2 to 39990 cd/m2 without using a dimmer.
3. Digital display, good display reproducibility, with data retention and peak hold function.
4. Low power consumption, 9V laminated battery can be used continuously for 100 hours.
5. Small metering probe with a diameter of 20mm. The diameter of the screen to be measured needs to be greater than 20mm, and the measured 
tilt angle should be less than 5 degrees.
6. Small and portable, easy to use.
