With the advancement of society, more and more people pay attention to their live experience. Many people put a sunscreen protective film on their car when they pick up the car. The film is mainly divided into the absorption film and reflection film. For different film sunscreen, effects are also different. For the car film, we generally use solar transmission meter to detect the window film.
What indicators will the solar transmission meter detect about the window film?
There are three main indicators: visible light, ultraviolet light and infrared light. Although excessive UV rays can damage our skin, UV rays also have a bactericidal effect. The heat in the sun is mainly from infrared rays, so if a solar film wants to achieve thermal insulation, it must be insulated from infrared rays. The transmittance of visible light is an essential test item for the solar transmission meter. Since the visible distance of a person is directly proportional to the light transmittance, the higher the light transmittance, the longer the visible distance. The lower the light transmittance, the shorter the visible distance. Therefore, the light transmittance of the automobile glass sun protection film directly affects the driving safety.
Measuring the automotive window film, we can use the Linshang LS182 solar film transmission meter. The main reasons are as follows:
1.Linshang LS182 solar film transmission meter has a wide range of applications, not only for automotive film, but also for building film, explosion-proof film, heat-insulating film, film glass and other materials.
2.The instrument has relatively comprehensive measurement parameters, which can measure infrared 950nm, infrared 1400nm, full infrared band and solar heat gain coefficient.
3.Using a large LCD screen, infrared and ultraviolet rejection rate display. The data is simple and easy to understand!
4.The instrument adopts parallel light design and the data is equally accurate when measuring thick glass.
5.Wide range of applications, suitable for exhibitions, quality inspection, production, inspection and other occasions.|
6.The instrument has real-time dynamic self-calibration function, which can realize automatic calibration after powering on.
