Trident – Thermal Conductivity Instrument

Inquire product

The Trident enables thermal conductivity testing of a wide range of solids, liquids, powders and pastes and offers maximum versatility by combining the modified transient surface swelling method (MTPS), the transient surface swelling method (TPS) and the transient line swelling method (TLS) in one modular system.

The MTPS high precision method is the simplest and most versatile. The TLS Needle method provides maximum robustness for those sticky situations. The Flex TPS method provides the greatest flexibility over experimental parameters with C-Therm’s flex sensors. Learn more about how each method works below.

3 methods for thermal conductivity:

  • MTPS
  • TLS Needle
  • Flex TPS

Modified Transient Plane Source (MTPS)

Simple and Precise. The MTPS method employs a single-sided sensor to directly measure thermal conductivity and effusivity of materials. The MTPS method has the highest precision, highest sensitivity, shortest test time, and is the easiest to use among all three techniques.

Transient Line Source (TLS) Needle

The TLS method employs a needle probe to characterize the thermal conductivity of viscous and granular materials. It is the most robust sensor for thermal conductivity testing.

Transient Plane Source (TPS) Flex

The TPS method employs a double-sided hot disc sensor to simultaneously determine thermal conductivity, thermal diffusivity and specific heat capacity of materials from a single measurement. TPS provides the user the greatest flexibility and control over experimental parameters and avoids the use of any contact agents. Recommended for more experienced users.
