This instrument is suitable for measuring the thermal conductivity, thermal conductivity and specific heat capacity of homogeneous slab, colloidal and powdery materials, under either dry or moisture conditions.
Features
simple configuraiton, high accuracy, fast test speed (about ten minutes per test); the thermal conductivity, temperature conductivity and specific heat capacity of the material can be measured at one time, and can be measured under different moisture conditions.
Standards
JGJT 12-2019 (instead of JGJ 51-2002) (Technical Specification for Lightweight Aggregate Concrete),
JG158-2004 "Powder Polystyrene Particle External Wall External Insulation System" and
JG/T283-2010 "Expanded Vitrified Microspheres" Determination of heat storage coefficient in Appendix B of Light Mortar.
Specifications
Principles
Based on the principle of unsteady heat conduction, heating in a short time in the experimental material will cause the temperature of the experimental material to change. According to the characteristics of the change, the thermal conductivity and thermal conductivity of the test material can be calculated through the solution of the thermal conductivity differential equation. Coefficient and specific heat capacity.
Instrument configuration: Including one DRM-II host, one software, one heater, one thermocouple, one thermos, and one Lenovo desktop computer (configured according to the contract).
