Best car window tint checker

Automotive solar film can be divided into different types according to different production processes, but in general, it is inseparable from the amount of heat insulation and ultraviolet light. At present, the common solar film can be divided into two types, so the solar film tester is also divided into more suitable for metal film, and more suitable for heat-absorbing film.

According to the material, the solar film can be divided into a metal film and a non-metal film (that is, an endothermic film). The metal film is often referred to as a magnetron sputtering metal film. In short, the metal particles are sputtered to a high speed in a magnetic field. The film is blocked by attaching multiple layers of different types of metal particles to block light in different wavelength bands. The reflective film is mostly a metal film. The heat control is better, but it is easy to shield the signal, which will affect the mobile phone, ETC and GPS signals. Non-metallic films are mainly based on heat-absorbing films, but excessive heat absorption can easily cause the temperature of automobile glass to rise faster.

How to choose solar film tester for different types of solar film

Most metal films have better 1400nm infrared rejection rate, while heat-absorbing films have better 940nm infrared rejection rate, so the Linshang car window tint checker is also divided into LS163A for testing 1400nm metal film and 940nm for absorbing heat LS163 of the membrane.
