LS182 Safety Anti-blast Window Film Transmission Meter
Shenzhen Linshang Technology has an LS182 safety anti-blast window film transmission meter, which can judge the light transmission performance and heat insulation and UV-blocking effect of the safety anti-blast window film based on the transmittance data of various light sources.
In 2014, Shenzhen Linshang Technology launched a series of demonstration-type safety anti-blast window film transmission meters. It is not difficult for customers to find that most instruments can only test the transmittance or barrier of three light sources of infrared, ultraviolet and visible light. However, this LS182 safety anti-blast window film transmission meter adds an infrared light source to the three-band instrument.
Why do we need to add an infrared light source?
Based on years of experience we have summarized some of the characteristics of the solar film. Most metal films have a higher infrared blocking ratio at 1400 nm, while most heat absorbing films have a higher thermal insulation rate at 950 nm. However, some customers want more objective infrared rejection data, so we have added these two infrared light sources to the LS182 safety anti-blast window film transmission meter.
The LS182 safety anti-blast window film transmission meter is designed with parallel light, which ensures the accuracy of the data when testing large thickness glass.
The current LS182 safety anti-blast window film transmission meter has three test stalls, the first test is the infrared rejection rate of 950nm, the third test is the infrared rejection rate of 1400nm, and the intermediate gear is the infrared light of 950nm and 1400nm. The average value of the infrared barrier rate. If a window film has a very high infrared ray rejection rate in both bands, it is basically confirmed that the thermal insulation performance of this safety anti-blast window film is excellent.
In addition, LS182 Safety anti-blast window film transmission meter can also test the SHGC (Solar Heat Gain Coefficient). For customers in the door and window industry, this parameter is a more common data.
