How to choose the right light meter for you
In short, an illuminance meter is an instrument that measures illuminance. It can measure luminous flux, brightness and other parameters with various front-end optical signal collection equipment. It is not only suitable for use in laboratories, quality inspection departments, and R&D departments, but can also be used for lighting effect evaluation in squares, stadiums, halls, lighting projects and other engineering projects. Illuminance meters are also one of the instruments that are widely used by everyone, and there are many types of illuminance meters at present, so everyone should know what kind of illuminance meter is suitable for them. What are the best conditions for using a light meter?
First of all, the illuminance meter itself must be small in size and light in weight.
Because the illuminance meter has many opportunities to be used and is often used in different places, the first prerequisite for a portable illuminance meter is small size and light weight. It is most suitable to use a illuminance meter for illumination control. The professional illuminance meter is portable and can be carried around, making it convenient for you to use it in different places. The digital LCD screen makes it easy to read readings quickly and accurately.
Then, the illuminance meter must be highly accurate
Whether the light meter is excellent or not is related to its accuracy. Of course, it is also closely related to its price, so it is necessary to buy a high-accuracy light meter at a reasonable price. For places with high illumination requirements, you can choose a large-range illuminance meter. It has automatic range setting, fast response, and a measurement speed of 1.5 times/second. It can quickly and accurately measure illuminance readings. This illuminance meter is cost-effective and is safe for your measurements.
Cosine compensation - everyone should also pay attention to it when selecting an illuminance meter
The brightness of the illuminated surface is related to the incident angle of the light source. By the same token, when measuring with a light meter, the incident angle between the sensor and the light source will naturally affect the reading of the light meter. Therefore, whether a good illuminance meter has the function of cosine compensation cannot be ignored.
With the improvement of living standards, people are paying more and more attention to quality control, and the application range of illuminance meters is getting wider and wider. Nowadays, illuminance meters can be used in measurement engineering, quality control, health prevention and control, and illumination measurement in various environments. Such as factories, schools, offices, transportation routes, homes and other occasions.
