Digital Light Meter Model: SHB7-7001

Simple introduction

So digital illuminance meter is a very convenient use instrument, the sensor and the instrument itself one combined

So light measurement brightness

So follow the German government PTB calibration (physical standards association) standard, and use a standard 2856 K light the lamp

So digital display: three and a half (maximum 1999)

So have the light sensor protection cap

So has the measurement data lock function

So easy to carry, equipped with carry bag

So wide measuring range, manual range choice (0-200/2000/20000/200000 lx)

So of the filter material shine silicon sensor

So keep the maximum function

The flux and intensity of illumination unit explanation:

Flux per unit time is to leave or through the surface, light quantity. Flux units are lumen (lm), inter69)ional unit system (SI) and the American unit system (AS) use the unit. If we will light through the space as a particle (photons), so to surface of the beam of flux and 1 second time intervals of the number of particles impact surface into a certain proportion.

Illuminance is on the surface of the flux per unit area. It to describe the level of surface lighting is very useful, and need not rely on the surface itself size measurements. International intensity of illumination unit is-lux (lx), it says every square metre 1 lumen. The intensity of illumination unit is feet candle (fc), equal to one lumen per square foot.
