How to choose a suitable light meter
The illuminance meter is a special instrument for measuring luminosity and brightness, and the illuminance is closely related to people's life. Sufficient light can prevent people from accidents. Conversely, too dark light can cause human fatigue far more than the eyes themselves. Uncomfortable or poor lighting conditions are therefore one of the leading causes of accidents and fatigue.
There are many models of illuminance meters on the market, and users are often at a loss when purchasing, and do not know which model is suitable for their own use. How to choose a light meter? In fact, as long as you choose products from regular manufacturers, there is no problem. Generally, pay attention to the following points:
1. It must be convenient to carry, because there are many opportunities to use the illuminance meter, and the timing of use is often in different places, so a portable illuminance meter with small size and light weight can maximize work efficiency.
2. The accuracy is high, so that you can give yourself professional data reference.
3. For measurement range and high-illuminance measurement, choose a large-range illuminance meter. Generally, the large-range range on the market can detect 400,000 Lux to meet the needs of high-illuminance detection. For low-light measurement, such as darkroom illuminance detection, it is necessary to choose a low-light illuminance meter, which can detect a minimum of 0.0001lux.
4. The illuminance meter is an instrument with very sensitive photosensitive elements. Therefore, if the user unit needs to issue a measurement verification certificate, it is best to choose a regular manufacturer to produce products, which can minimize the occurrence of unqualified inspections.
