Thermal Property Testing

ThermTest maintains a full-service thermophysical measurements laboratory servicing industrial, academic, environmental, government labs and commercial clients in North America and international markets.

ThermTest continues to upgrade laboratory instrumentation to meet the testing needs of our clients. We are especially proud to be able to offer the sale of multiple instruments and methods for measuring thermal conductivity, which is dependent on your sample type, testing temperature range, and sample dimensions.

Complete results report delivery in one week. We also offer one day service if needed. In addition, if you test more then three samples, we pay your shipping costs.
