A transient plane source (TPS-3) for testing the thermal conductivity, thermal diffusivity and specific heat of solids, pastes and powders for customers with a limited budget.
Best for solids, pastes, and powders
We designed the transient plane source (TPS-3) for testing the thermal conductivity, thermal diffusivity, and specific heat of solids, pastes and powders for customers with a limited budget. The TPS-3 includes the standard TPS Sensor and software for use in combination with the Keithley 2400/2401 Source Meter. The TPS-3 can be offered as a package with a Keithley meter or for use on your own.
The basic theory is that the sensor, which is placed between two pieces of the same sample, is electrically connected to a power supply and sensing circuit. A current passes through the sensor and creates an increase in temperature recorded over time. The heat generated is then diffused into the sample at a rate dependent on the thermal transport characteristics of the material.
