We are excited to announce that Partners now has three high-tech Linshang LS300 thermal insulation testers available in our offices in Sofia, Plovdiv, and Varna.
This professional device is specifically designed to measure the effectiveness of 3M thermal insulation and solar control window films. With the LS300 from Linshang Technology, a leading manufacturer of measuring instruments, our clients can see real-time temperature differences between standard glass and glass covered with 3M film.
How Does the Thermal Tester Work?
The LS300 uses a 250W infrared lamp to simulate solar radiation on two glass panels—one with 3M solar control film and one without any coating.
✅ Accurate Measurements – Digital displays show the temperature in both chambers, clearly demonstrating 3M film’s ability to block heat and UV rays. ✅ Energy Efficiency Testing – The LS300 measures not only temperature differences but also infrared and visible light transmittance, key indicators of film performance. ✅ Hands-on Demonstration – Customers can see and feel the difference when applying 3M solar control films in real conditions.


Why Choose the Linshang LS300 Thermal Tester?
With the LS300, every customer can personally experience the benefits of 3M solar control films for buildings and vehicles—their efficiency in reducing heat, improving energy savings, and protecting interiors from UV rays and fading.
Linshang Technology has over 10 years of experience in developing innovative measurement tools. The LS300 is one of the most reliable testers for demonstrating the functionality of solar control films, offering high accuracy and ease of use.
