Automatic Portable Digital Illuminance Meter For the Visible Light Illuminance

The ST-85 automatic range digital illuminance meter adopts SMT technology and high-precision low-power chip. The illuminometer instrument cover is streamlined design. The built in detector has stable performance and strong applicability due to strict spectral and angular characteristic correction. It can be used to measure the visible illuminance emitted by incandescent light, fluorescent light, high-pressure sodium light, metal halide light or LED. ST-85 is widely used in industry, agriculture, construction, environment, health, scientific research and other
