GHP Guarded Hot Plate Tester
Test equipment for GHP insulation material ideal, according to GB/T 10294&ISO 8302 standard, its basic principle is: build a one-dimensional uniform heat flux in two uniform plate which have parallel surface,the material’s thermal resistance R=A(T1-T2)/Φ and thermal conductivity λ=Φd/[A(T1-T2)] are measured by test the thermal conductivity, thickness,hot surface temperature, cold surface temperature and effective heating area,.
Test temperature: RT~1200℃
Test accuracy: 0.1~2%
Sample size: 300×300×(10~100)mm;500×500×(10~150)mm
Thermal resistance R: 0.1~0.02 m²k/W
Coefficient of thermal conductivity: 0.01~5.0 W/m•k
