THW-L2
Designed with speed and operational simplicity in mind, the Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896-19. In less than 2 seconds, a single measurement of small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. 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. The THW sensor consists of a 60 mm heating wire that is fully inserted into an isothermal sample. A constant current source (q) is used to heat the sensor wire and the temperature rise is recorded by monitoring the change in electrical resistance of the wire. The slope (m) is determined from the plot of temperature rise vs. logarithm of time and is used in the calculation of thermal conductivity (λ). Liquid samples of high thermal conductivity will have a lower slope, while liquid samples with low thermal conductivity will have a higher slope.

Thermal Analysis
The TORC (Thermo-optical Oscillating Refraction Characterization) technique applies decades of know-how in optical instrumentation to thermal analysis in a novel and unique way. The technique requires minimal sample preparation at maximal tolerance for sample properties. You can determine the coefficient of thermal expansion, glass and phase transitions as well as polymerization for various samples: liquids, gels, pastes, and certain solids. For example: cured and uncured resins, adhesives, glues, etc. can easily be characterized. Both thermal and time-dependent processes can be monitored with minimal effort.
