THW-L1 Transient Hot-Wire Liquid Thermal Conductivity & Diffusivity Equipment

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. The THW-L1 was designed with speed and operational simplicity in mind. With a single measurement of 1 second in duration, small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity, thermal diffusivity, and specific heat.

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.

DSC L600 Differential Scanning Calorimeter

Differential Scanning – Calorimeter

The Differential Scanning Calorimeter (DSC-L600) is a powerful thermal analysis instrument that measures the heat flow of a sample as a function of time or temperature. The DSC-L600 has been designed to be a cost-effective instrument that is well suited for research or QC applications. The instrument communicates with the PC via a RS232/USB connection. The specially designed heat flux plate has demonstrated more than twice the sensitivity than other heat flow type DSC’s on the market. The reproducibility is excellent, and the noise level is virtually unnoticeable due to a precision high gain, low noise differential amplifier.

  • High-sensitivity heat flux design
  • A stable and reproducible baseline
  • Temperature range: -150°C to 725°C

Thermogravimetric Analyzer

The Thermogravimetric Analyzer TGA-1000/1500 is a thermal analysis instrument that measures weight changes as a function of temperature or time. The system allows for multiple heating, cooling, and isothermal segments to be linked together to achieve a complex profile. Automatic gas switching is also supported during the temperature program. The vertical hangdown design offers stable and smooth weight readings to be recorded during the experiment. The TGA’s small mass furnace responds quickly to changes in the temperature profile and cools down quickly for fast turn around between experiments. Typical analyses for a TGA-1000/1500 include percent weight loss, onset temperature calculations and residual weight. The TGA utilizes the advanced and easy to use Infinity Pro Windows software. The acquisition program sets up the experiment and plots the real-time data. The Analysis program performs all calculations and provides hard copy outputs.
