Thermal Analyser

he KD2-Pro is a fully portable field and lab thermal properties analyser. It uses the transient line heat source method to measure thermal diffusivity, specific heat (heat capacity), thermal conductivity and thermal resistivity. Sophisticated data analysis is based on 30+ years of research experience on heat and mass transfer.

The KD2 Pro uses 3 sensors to measure thermal diffusivity, specific heat, conductivity and resistivity. The KD2 Pro allows unattended (user programmable) measurements and on-board data storage with space for over 4,000 measurements.

Corrects for Temperature Drift

Temperature changes of a thousandth of a degree per second (for example someone walking into the lab) destroy the accuracy of thermal properties calculations. Unlike other thermal needle systems, the KD2 Pro corrects for linear temperature drift that can account for large errors.

Excellent Accuracy

The compact KD2 Pro controller is much more than a simple readout for time and temperature. A proprietary algorithm fits time and temperature data with exponential integral functions using a nonlinear least squares method. This full mathematical solution delivers thermal resistivity to within ±10%.

Complies with ASTM, IEEE, SSSA Standards
