Resistivity KD2 Pro Thermal Conductivity Meter

Decagon KD2 Pro Thermal Conductivity Meter

Item # 108500

The KD2 Pro is a fully portable field and lab thermal properties analyzer. It uses the transient line heat source method to measure thermal conductivity, resistivity, diffusivity, and specific heat. We find our clients in the underground power engineering community really like it for design parameters in solar and wind-farm tower arrays.

It consists of a handheld controller and sensors that can be inserted into the medium you wish to measure. The single-needle sensors measure thermal conductivity and resistivity; while the dual-needle sensor also measures volumetric specific heat capacity and diffusivity. Unlike other thermal needle systems, the KD2 Pro corrects for linear temperature drift that can cause large errors.
