The C-Therm Trident is a thermal conductivity measurement system used for testing the thermal properties of a wide range of materials, including liquids, powders, solids, and pastes. The system utilizes the transient plane source (TPS) method, which involves heating a thin, flat sensor that is in contact with the sample and measuring the resulting temperature rise over time. This allows the system to accurately determine the thermal conductivity of the sample. The C-Therm Trident is a portable, easy-to-use system that can be used in both laboratory and field settings, making it a versatile tool for a wide range of applications in materials science, geology, and engineering.
