The quality of the solar film on the market is now uneven, and many solar film manufacturers sacrifice light transmittance for higher infrared and ultraviolet blocking rates. However, the light transmittance in some areas has the minimum. The vehicle management system also uses a tint meter to test the light transmittance. How to Read a Tint Meter?
The summer vacation is hot, and many car owners choose to put their own private cars with thermal insulation and UV-blocking solar film. However, the light transmittance of the automobile glass after attaching the film will be lowered, which is why the traffic police often use the instrument to test the light transmittance of the front windshield of the automobile.
In some areas, the light transmittance of the front windshield of the car should not be lower than 70%, and the light transmittance of the side glass of the van should not be lower than 50%. Therefore, it is necessary to use the tint meter for testing because the naked eye cannot distinguish the transmittance of the glass.
How to use the tint meter to detect the transmittance of the glass?
The reading of tint meter
The figure below shows the two display interfaces before testing and when testing the glass. It can be seen that the light transmittance before testing is 100%. At this time, there is no test object between the host and the slave tint meter, so the light can pass through the test hole and be received by the detector. The tint meter in the picture on the right is testing a glass sample. At this time, the light transmittance is 90%, which means that the light intensity passing through the glass is 90% of the incident light intensity.
From the above explanation, it is believed that the reader has understood how to read a tint meter and the meaning of the data. This tint meter is mainly used in traffic police brigade and vehicle management, automobile 4S shop and other places. If you have any other questions, please feel free to contact us.
