THW-L2 Thermal Conductivity Instrument Meter Transient Hot Wire

Transient Hot Wire

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.

Hot Disk Transient Plane Source

The Hot Disk TPS is widely used for the accurate measurement of absolute thermal conductivity, thermal diffusivity, and specific heat of solids, liquids, pastes, and powders. This non-destructive method has a thermal conductivity testing range of 0.005 to 1800 W/mK and can be used to measure bulk properties of homogeneous and heterogeneous materials, as well as directional properties for anisotropic materials. This versatility is greatly appreciated by academic and commercial users alike, which has led to more than 1000 publications on a wide variety of applications.

Transient Plane Source – Effusivity Meter

The TPS-EFF (Transient Plane Source-EFFusivity) is a portable meter for direct determination of thermal effusivity of textiles and other low effusivity materials, in accordance with ASTM D7984-16. With a single measurement of 2 or 10 seconds in duration, materials can be accurately measured for thermal effusivity.

Guarded Heat Flow Meter

The Guarded Heat Flow Meter (GHFM-02) follows ASTM E1530-19 for testing thermal resistance and thermal conductivity of solids, such as metals, polymers and composites. The easy to operate GHFM-02 follows the trusted steady-state approach, with the addition of a guard to limit the effects of lateral heat loss. This design, allows testing of a wide range of materials with low to medium thermal conductivity.
