    What is Thermal Resistance

    Thermal resistance (symbol R) is a measurement of a temperature difference by which an object or material resists heat flow. It is the reciprocal of thermal conductance. Its SI units are kelvins per watt or the equivalent degrees Celsius per watt.

    How to test for thermal resistance?

    Thermtest offers various thermal resistance testing services. Our thermal resistance measurement methods cover a wide range of temperature and sample types. If you have any questions about testing, please contact us and we will answer as quick as possible.

    Calnesis

    “Calnesis is a company that provides physico-chemical property measurements. We like challenges and our customers consult us most of the time for original experiments. Sometimes our apparatus or techniques are not enough. To satisfy our customers needs, we have to find solutions in other labs to complete our offer. The point is that we have to find the same level of expertise as we sell. That is what we have found with the team at Thermtest, a very professional partner.”
