The digital luxmeter is a professional instrument for measuring illumination and brightness, which can be used in light intensity measurement engineering, quality control, illness prevention and treatment and measurement of light intensity in all kinds of environments such as factories, schools, offices, transportation routes, families, etc.

Digital Lux Meter possesses the following features:

1. Measure current illumination and temperature.
2. Measure difference value, max value and min value.
3. Switch between illumination and temperature unit.
4. The measurement range is (0~200000) lux, auto switch of
measurement gear.
5. Automatic storage and manual storage of illumination data.
6. Setting of automatic power off.
7. Backlight and data holding.
