How to choose the right type of illuminance meter
Illuminance meter in short is an instrument to measure illuminance, with a variety of front-end light signal acquisition equipment can measure luminous flux, brightness and other parameters. It is not only suitable for laboratory, quality inspection department, research and development department, but also can be used for plaza, stadium, hall, lighting project and other engineering projects to evaluate the lighting effect. Illuminance meter is also widely used by one of the instruments, and there are many types of illuminance meter, then you should know what kind of illuminance meter suitable for themselves. Illuminance meter use conditions * good to have what?
First of all, the illuminance meter itself should be small in size and light in weight.
Because the illuminance meter is used very much, the use of the time is often in different places, so portable small size, light weight for the prerequisites of the illuminance meter. The use of illuminance meter for illumination control * appropriate, professional illuminance meter portable design, can be carried around, convenient for you to use in different places, digital LCD display, easy to quickly and accurately take readings.
Then, the illuminance meter to be accurate
Whether the illuminance meter is good, and its accuracy has a relationship. Of course, it is also closely related to its price, so a reasonable price to buy a high accuracy illuminance meter is necessary. For the illumination requirements of the place can choose a large range of illuminance meter, automatic range setting, fast response, measuring speed 1.5 times / sec, fast and accurate measurement of illuminance readings, this illuminance meter cost-effective, is your measurement of **.
Cosine compensation - everyone in the selection of illuminance meter should also pay attention to
The brightness of the illuminated surface is related to the angle of incidence of the light source. For the same reason, when using the illuminance meter to do the measurement, the sensor and the light source incident angle will naturally have an impact on the reading of the illuminance meter. So a good illuminance meter whether cosine compensation function can not be ignored.
With the improvement of the standard of living, people pay more and more attention to quality control, illuminance meter application is more and more extensive, now illuminance meter can be used for measurement engineering, quality control, health prevention and control and a variety of environments in the light illuminance measurements, such as factories, schools, offices, traffic routes, families and other occasions.
