Overview

Japanese Minolta LS-100/LS-110 Brightness Meter $r $n

Product Details

LS-110

feature

The high portability and handheld design enable measurement under various brightness conditions. The non flowing SLR (single lens reflex) optical system can achieve high-precision measurement. The opening angle is 1/3 °, supporting measurement of extremely small target areas.

purpose

Measure the brightness of CRT, LED, and EL.
Measure the brightness of highways and tunnels
Measure railway system signals
Measure road and airport signals
Measure illuminance and outdoor markings
