TheHigh-Precision Material Thermal Conductivity Tester is suitable for steady-state thermal performance evaluation of materials with low to medium thermal conductivity, including:

Thermal insulation materials

Plastics and polymer-based materials

Rubber and elastomer materials

Aerogel panels and advanced insulation boards

Vacuum glass and building energy-saving materials

Solid materials and powder materials (with appropriate sample configuration)

The instrument is widely used in universities, research institutes, quality inspection laboratories, and industrial material testing facilities for thermal conductivity and thermal resistance analysis.

Standards

The instrument is designed and operated in accordance with the following international and national standards:

GB/T 10295-2008

Thermal insulation — Determination of steady-state thermal resistance and related properties — Heat flow meter method

ASTM E1530

Standard Test Method for Evaluating the Resistance to Thermal Transmission of Materials by the Guarded Heat Flow Meter Technique

ASTM C518-04

Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus
