I. LS301 Solar Film Meter Introduction
Linshang LS301 thermal insulation film temperature tester is a temperature test box that can directly demonstrate the solar film thermal insulation rate and energy-saving glass thermal insulation rate. It can also test the thermal insulation effects of two different materials while testing the thermal insulation rate of 940nm , Expressed by temperature.

III. LS301 Solar Film Meter Characteristics
1. Using 150W genuine Philips infrared light with better insulation effect.

2. The LS301 solar film temperature meter can simultaneously display the real-time temperature value and the insulation rate of tested materials during the test.
3. Now we will demonstrate how to read and understand the data accordign to the following pictures
(1) The left side of the figure below is the data when no test sample is placed and the power is on. You can see that the real-time temperature on both sides is 20.8 ℃ and the heat insulation rate is 0.0%.
(2) After placing 2 test samples, the instrument will immediately display the heat insulation rate of the glass. After the light is turned on, the insulation data will be locked on the interface. (Be sure to put the test sample before turning on the light, otherwise the insulation rate cannot be tested.)
(3) After the light is turned on, the real-time temperature above the instrument will rise. As can be seen from the right side of the figure below, the real-time temperature will rise to 38.6℃ and 30.7 ℃, respectively.

VIII. FAQ about LS301 Solar Film Meter
-
1. Why is the shipping cost of this device so expensive?
The device is made of stainless steel, with a net weight of 13kg, so the freight is relatively high.
-
2. What is the difference between LS300 and LS301?
LS300 can display the real-time temperature and temperature difference before and after powering on the IR lamps.
LS301 can display the real-time temperature and heat rejection rate. (Actually it's the 950nm IR rejection rate of the sample)
-
3. What is the suitable glass size for LS300 and LS301?
The glass size is 20*16cm, the thickness should not exceed 5mm.
-
4. What is the specification of the plug? Can you provide plugs of other specifications?
It uses a three-wire socket, which is a 220V power socket for household appliances in China. Currently, plugs of other specifications are not provided, please purchase adapters or transformers yourself.
