An ideal illuminometer should meet the following conditions:

Firstly, the illuminometer itself should have a small volume and light weight

Because there are many opportunities for the use of illuminometers, and their timing is often in different places, portable illuminometers with small size and light weight are prerequisites.

Then, the illuminometer needs to have high accuracy

The quality of an illuminometer is related to its accuracy. Of course, it is also closely related to its price, so it is necessary to buy an accurate illuminance meter at a reasonable price. For places with high lighting requirements, a large range of illuminance meters can be selected.

Cosine compensation - everyone should also pay attention to timing when selecting illuminance

The brightness of the illuminated surface is related to the angle of incidence of the light source. Similarly, when using an illuminometer for measurement, the angle of incidence between the sensor and the light source naturally affects the reading of the illuminometer. So whether a good illuminometer has cosine compensation function cannot be ignored.

With the improvement of living standards, people are paying more and more attention to quality monitoring, and the application range of illuminance meters is becoming wider. Currently, illuminance meters can be used for measuring engineering, quality control, health prevention and control, and various environmental lighting illuminance measurements, such as in factories, schools, offices, transportation routes, homes, and other occasions.
