The country also clearly stipulates that the light transmittance of the automobile film should reach 70% to meet the requirements. If you do not know whether the film is up to standard, the most reliable is to verify the quality of the car film through the data tested by the LS110A Split Transmission Meter.
The most three important factors to verify the quality of the explosion-proof membranes is the light transmittance, infrared rejection rate and ultraviolet rejection rate.
The most important requirement for the window film is the light transmittance, especially on the front windshield. The national traffic safety law stipulates that the visible light transmittance of the front windshield must be greater than 70%. If the light transmittance is too low, it will cause blurred vision when driving, and seriously reduce the safety factor of driving. When testing the explosion-proof film, the light transmittance must be tested.
The infrared rejection rate of the explosion-proof membrane is also the thermal insulation performance. Whether it is summer or winter, it is also necessary to affix the explosion-proof membrane, which is to prevent the window glass from bursting due to the influence of temperature. The higher the infrared rejection rate, the more solar heat is blocked, which can reduce the use of air conditioners and achieve environmental protection.
The greater the intensity of ultraviolet radiation, the more damage will be caused on the skin. It will also cause dizziness and headache. Ultraviolet light also accelerates the aging and fading of interior jewelry. Therefore, the UV rejection rate of high-quality explosion-proof membrane can reach more than 95%, and can be easily identified by using the LS110A Split Transmission Meter.
The Linshang LS110A Split Transmission Meter can test these three data, so that you can put the explosion-proof film on the car with more confidence.
