Use Window Tint Light Meter to Measure Glass Transmittance

In order to save energy and protect the privacy of the car, most car owners will choose to put a solar film on their cars. Experience has found that some owners do not know enough about the role of the front windshield film, they think that the front windshield film is not necessary. Or they would worry that the front windshield film will affect the vision. 
       Actually, not all films will hinder driving sight. The "Technical Conditions for Motor Vehicle Operation Safety" implemented on September 1, 2012 stipulates that "the visible light transmittance of the front windshield glass is measured by a window tint light meter should be more than 70%. All window glass is not allowed to have a mirror reflective sunscreen. " Therefore, the front window film with a light transmittance of more than 70% and a visible light reflectance of less than 10% can be affixed to the front glass, which will not affect the driving vision.
     The light transmittance is an important consideration parameter for automotive film. The light transmittance of automobile front barrier film can be measured using a window tint light meter. As the car front glass transmittance measuring instrument detects the light transmittance, it can also measure the infrared transmittance and ultraviolet transmittance after the car is filmed. Because infrared rays are the main source of heat in sunlight. The transmissivity measurement can simultaneously detect the heat insulation and UV radiation protection effects of automotive films. Eliminate the worries of car owners after the film.
     The use of a professional front film not only can block a large area of heat from entering from the front of the car, but also can reduce the burning sensation of the hot sun. At the same time, it can effectively reduce the temperature inside the car and protect the car interior. You know, the high-quality front barrier can easily block 99% of the ultraviolet rays harmful to the human body, so that the driver will not suffer skin damage due to long-term exposure to ultraviolet rays while driving.
      In addition, the high-quality front barrier can also effectively reduce the glare of the driver during driving and will not affect the driver's field of vision due to the glare. More importantly, if you put a front screen on your car, if the vehicle accidentally occurs during the operation, the professional front screen can also prevent the glass from splashing, because it will stick the broken glass in place. Therefore, it is necessary to measure the light transmittance with a window tint light meter.

Many people like to stick a dark solar film or a reflective solar film to prevent outsiders from seeing the inside of the car to protect the privacy of the car. However, we must know that the visible light transmittance of dark-colored solar films is very low. Like those dyed films on the market, their light transmittances are very low. They are based on the principle of blocking the energy of visible light. Not to mention ultraviolet rays, it is a true "light-shielding film", which seriously affects driving safety. Therefore vehicles with these solar films will not pass the safety inspection.
     Therefore, when the owner considers purchasing the glass film, we can use the window tint light meter to measure the real data of the car front film transmittance. We generally use the LS110 window tint light meter. The LS110 window tint light meter adopts a split design, which is more suitable for detecting automobile windshields. The accuracy can reach within ± 2%. This window tint light meter has high measurement accuracy and simple operation.
