XRY-2A Regenerative Coefficient Tester

Introduction

The instrument can be measured simultaneously in one test out different coefficients of thermal storage moisture state of the material, thermal conductivity, thermal diffusivity and specific heat, the device is simple, accurate, fast test (a test about ten minutes), References: JGJ51-2002 (lightweight aggregate concrete technical specification) and the like. In non-steady heat conduction based on the principle, heat it up briefly in the experimental material, the temperature of the test material is changed, according to the characteristics of the change, by solving differential equations of heat conduction, heat storage coefficient can be calculated test material, thermal conductivity , thermal diffusivity and specific heat.
