Hollow Glass Steady State U-value Tester Insulation Materials Steady-State Thermal Resistance Properties Test Machine
Product Description
The hollow glass steady-state U-value tester is used to measure the steady-state U-value of hollow glass. According to the requirements of the standard GB/T22476 "Calculation and Measurement of Steady-State U-Value (Heat Transfer Coefficient) of Hollow Glass", the steady-state U-value of hollow glass is measured by the protective heat plate method. The hollow glass steady-state U-value tester is applied to various manufacturers of hollow glass materials, relevant quality inspection departments and units, universities and research institutes, and other scientific research units and institutions.
According to standards
GB/T10294-2008 "Determination of Steady-State Thermal Resistance and Related Properties of Insulation Materials"
GB/T22476-2008 "Calculation and Measurement of Steady-State U-Value (Heat Transfer System) of Insulating Glass"
