940nm window tint meter is recommended to measure absorbing window film (glass)
1400nm window tint meter is recommended to measure metallic film or ceramic window film (glass)
LS182 window tint meter can be used to test absorbing film, metallic film and ceramic window film
If you need to measure both the rejection rate and the transmittance (visible light transmission), you can choose window tint meter LS163 or LS163A.
III. FAQ about window tint meter
1. Which test result is more accurate between window tint meters with 940nm and 1400nm light source?
No matter which window tint meter is used, the test data is objective and accurate.The wavelengths of 940nm and 1400nm are relatively representative wavelengths of sun spectrum.
Most of the absorbing films (heat-absorbing films) have better infrared blocking effect at 940nm, while the magnetron sputtering reflection film has better blocking effect at 1400nm such as metallic film and ceramic nano window film.
Please choose the right window tint meter based on your own window film category.
2. The differences between a metalic film and a heat-absorbing film?
The metalic film is produced by a magnetron sputtering process. A large amount of metal elements are added for a good reflection ability to the infrared film. It is insulated by the principle of reflecting infrared rays.
The heat-absorbing film is added with an infrared absorber during production and the infrared is absorbed by the film. It is insulated by the absorption principle and secondary heat radiation will be generated after the heat absorption is saturated.
