1. What is the difference between a metal film and an endothermic film?
The metal film is produced by a magnetron sputtering process. A large amount of metal elements are added and the has a good reflection ability to the infrared film. It is insulated by the principle of reflecting infrared rays. The absorption film is added with an infrared absorber during production and the infrared is absorbed by the film. It is insulated by the bsorption principle and secondary heat radiation will be generated after the heat absorption is saturated.
2. Why are 1400nm instruments so much more expensive than 940nm instruments?
It's all about the cost of raw materials. The cost of a 1400nm light source and receiver is much higher.
3. Can the window film transmission meter measure the insulation rate?
Our instrument measures the infrared rejection rate. The higher the infrared rejection rate, the higher the thermal insulation rate. Because visible light also has a small amount of heat, in the strict sense, the heat insulation rate needs to integrate visible light, infrared and ultraviolet heat insulation data. Ultraviolet heat is very small and visible light is beneficial. Therefore, infrared is the main source of heat, so the infrared rejection rate is basically equivalent to the thermal insulation rate.
4. What is the difference between LS300 and LS301?
The LS300 measures the real-time temperature (degrees Celsius) and the temperature difference. The LS301 has an additional function to measure the infrared rejection rate of 940nm than the LS300. At the same time, the LS301 also measures the real-time temperature value.
5. What is the difference between the new and old LS101?
The parameters of the new and old models are basically the same, both of which can measure three parameters of heat insulation, UV rejection and light transmission.
The old model can only be used when plugged in. It is a digital tube display. The new model is an LCD display. It uses 4 AA
batteries and has a USB interface on the instrument. It can be directly powered by a power bank or 5V charging head.
The light source of the old LS101 is a point light source, which is only suitable for films and thin glass; the new LS101 uses
a parallel light path design and thick glass can also be tested.
6. Do you offer OEM and ODM service?
Yes. We can supply OEM and make customized design for any specific application.
7. How can we guarantee quality?
Always a pre-production sample before mass production; Always final Inspection before shipment;
