Comprehensive Analysis of Illuminance Meter: Operating Principles, Applications, and Selection Guide

Principle of Illuminance Meter Testing: An illuminance meter is a device used to measure illuminance (light intensity), based on the principle of photoelectric effect. The photovoltaic cell used in illuminance meters is a type of photoelectric component that directly converts light energy into electrical energy. When light strikes the surface of the photovoltaic cell, it passes through a metal fil...
