The Guarded Hot Plate Thermal Conductivity Tester employs the classic guarded hot plate steady-state method principle. Its guard heating structure effectively eliminates edge heat loss, delivering high-precision and repeatable test results for low thermal conductivity insulation materials.
Equipped with an independent hot plate and cold plate temperature control system, high-precision temperature sensors, and professional Windows testing software, this instrument supports automatic data collection, calculation, curve display, and test report output.
Suitable for testing flat slab-shaped thermal insulation and low heat-conductive materials including:
