What are the advantages of light meter
● Compact Size, Light Weight
The illuminance meter has a very broad range of applications, and it is frequently used at various times and locations. Small size and light weight are hence the foremost requirements for the portable illuminance meter.
● Accuracy
The accuracy of the lux meter is directly related to how accurate it is. It is vital to purchase a lux meter with excellent accuracy at an affordable price because, of course, it is also closely tied to its price. The mistake should typically not be higher than 15%.
● Color Compensation
The types of light sources are all-encompassing. Some focus on red high-pressure lamps with longer wavelengths, or blue-violet ones with shorter wavelengths such as Daylight fluorescent lamps; there are also more evenly distributed ones such as incandescent bulb series. The sensitivity of the same illuminance meter to different wavelengths may be slightly different. Therefore, appropriate compensation is necessary.
● Cosine Compensation
Everyone knows that the brightness of the illuminated surface is related to the incident angle of the light source. In the same way, when measuring with a light meter, the incident angle between the sensor (Sensor) and the light source will naturally affect the reading value of the light meter. Therefore, whether a good illuminance meter has the function of cosine compensation cannot be ignored.
