Transient Hot Wire – THW-L1

The Transient Hot Wire (THW-L1) is a liquid thermal conductivity equipment for direct determination of thermal conductivity, thermal diffusivity, and specific heat capacity of liquids and pastes in accordance with ASTM D7896-19. This versatility is greatly expanded with the addition of Thermtest’s proprietary Temperature Platform (TP) which is appreciated by academic and commercial users alike.

The transient hot wire (THW) has been used for the testing of liquids for more than 30 years, making it one of the most published methods for measuring thermal conductivity of liquids available.

Transient Hot Wire THW-L2

The Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is a portable measurement system for direct determination of the thermal conductivity of liquids and pastes. The THW-L2 follows international standard ASTM D7896-14, and was designed with speed and operational simplicity in mind. Using a non-stationary measurement approach, the THW-L2 uses rapid test times to limit convective effects for samples with a wide range of viscosities.

Steady-State ThermoReflectance Fiberoptics

Steady-State ThermoReflectance Fiberoptics (SSTR-F) combines the technological power of laser based thermoreflectance experiments with the proven measurement capabilities of steady state thermal measurements. Utilizing small measurement volumes allows for rapid steady state measurements of materials with thermal conductivities ranging from as low as 0.05 Wm-1 K-1 up to 2,500 Wm-1 K-1. In addition to the wide range of accessible thermal conductivities, SSTR-F can accommodate sample sizes as small as a few hundred microns. Exploiting recent advances in fiber-optic components and laser systems allows for a safe, user-friendly tool capable of high throughput thermal conductivity measurements.
