Comparison Between Solar Film Tester and Solar Films Seconds Kill Device

Recently a lot of new and old customers come to consulting solar film tester always incidentally asked "you did sell Solar Films Seconds Kill Device? It is said that the Solar Films Seconds Kill Device can in just a few seconds to identify solar film quality, can be described as the solar film tester STAR. " Is this really in fact? Now let me  explain to you the work principle and the use errors of the Solar Films Seconds Kill Device:

Solar Films Seconds Kill Device is by iodine tungsten lamp test film for instantaneous irradiation, through solar film is heated by the heat variable to determine the extent to which the material of high and low melting point. Simply said, is through a great power of the lamp, so that the rapid rise in temperature to 200 degrees Celsius, to heat the solar film.
       But why can it be different from the metal and nonmetal film (non-metallic film will be burned, the metal film is not)? That is because the metal film containing metals, high melting point, and reflective heat insulation performance is good, so it is not easy to coking; rather than the metal film material containing metal composition, melting point is low, easy to coking at high temperature.
       We can see from the principle of the Solar Films Seconds Kill Device, it is only a simple and quick determination of the melting point of the solar film material, but the overall performance of the solar film (such as solar energy, the total rejection rate, transmittance, reflectance, UV rejection, etc.) can not come to a scientific and effective decision,
       The disadvantages of the Solar Films Seconds Kill Device:
       1: Solar Films Seconds Kill Device test time must be controlled within 3 seconds, 3 seconds after the automatic power off. That is because, whether it is a metal film or non-metallic film, can only accept the high heat for about 3 seconds, as long as the test time is longer, any film will be coking.
       2: Solar Films Seconds Kill Device is only a simple and fast determination that with high or low melting point of solar film material, but the overall performance of the solar film, such as the transmission performance, the ultraviolet performance, heat insulation performance can not be a scientific and effective decision.
       3: The normal use of the solar film environment temperature is much lower than the test temperature of the Solar Films Seconds Kill Device. there is no real significance to judge good or bad of solar film with the Solar Films Seconds Kill Device
       Advantages of using the solar film tester:
       1: Can test the ultraviolet 365nm, visible light 380-760nm, infrared 1400nm or 950nm three band.
       2: Direct display of UV rejection, infrared rejection and transmittance, and easy to test and data reading.
       3: Small size, easy to carry, 5V DC/AC power supply, can also power supply by lithium battery.
       The Solar Films Seconds Kill Device is with only one single melting point parameter, by giving human a visual experience, thus to mislead consumers, so it is not correct to use the Solar Films Seconds Kill Device to assess the advantage and disadvantages of the solar film. It is a overall and comprehensive evaluation of the comprehensive index, such as transmittance, UV, heat insulation and so on. This requires a professional solar film tester to determine.
