Transient Hot-Wire THW-L2
The Transient Hot-Wire (THW-L2) is a portable thermal conductivity meter for measurement of liquids.
Best For Liquids
The Transient Hot Wire (THW-L2) is a portable liquid thermal conductivity meter for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896-19. The THW-L2 was designed with speed and operational simplicity in mind. With a single measurement of less than 2 seconds in duration, small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. The THW-L2 utilizes a non-stationary measurement approach and rapid test times to limit convective effects for samples with a wide range of viscosities.
