How to Select Car Window Tint Tester?

Car window tint tester, also known as car window tint measuring device, can be used to measure the visible light transmittance (ie light transmittance), infrared rejection rate and ultraviolet rejection rate of automobile glass，stick-film glass, window films. Window films can be classified as infrared rejecting window tint, ceramic window tint, metallized window tint, dyed window tint, etc. 

Through measurement, we can intuitively see the transmission performance of window films. The VLT, UV and IR performance is different for automobile front windshield and side windshield.  For the car front windshield, the visible light transmittance must be greater than 70% in China to meet the regulation. And the front windshield should also has high IR and UV rejection performance. However, for the car side windshield, the visible light transmittance requirement is much lower.  The UV and IR performance is important. This article will introduce the use and classification of car window tint tester in detail, hoping to help users choose a suitable car window tint tester.

1. Measure the transmittance of automotive window tint

The visible distance of the driver will decrease as the transmittance decreases. When the visible light transmittance of the car glass is above 70%, the visible distance of the driver is less affected by the transmittance, which is also visible to the human eye. Therefore, for safety reasons, the visible light transmittance of the car can't be lower than 70%. Car window tint tester can measure the visible light transmittance, UV and IR rejection performance of automobile windshield and directly display it in the form of percentage. The data is intuitive and easy to understand.

2. Measure infrared and ultraviolet rejection rate

Car window tint tester can measure infrared rejection rate and ultraviolet rejection rate. Infrared rejection rate can reflect the thermal insulation performance of automobile glass. Ultraviolet rejection rate can reflect the ultraviolet blocking performance of automobile glass. In summer, the ultraviolet and heat in sunlight are very high, so high-quality automotive glass films usually have a high infrared and ultraviolet rejection rate. If you want to know the details about how to measure automobile window tint using Linshang car window tint tester, please read "Window Tint Checker Test Automotive Stick-film Glass".

These three split-type car window tint testers can be divided into two parts: main machine and auxiliary machine. When measuring, they need to attach on both sides of the automobile glass to complete the measurement. In addition to measuring window film, thermal insulation glass and automobile side windshields, these three car window tint testers can also measure front and rear windshields of automobiles. If you only want to measure the visible light transmittance of glass, PC materials and so on, you can choose light transmittance meter.
