1. Introduction
The RNLY / DRY-300F series intelligent thermal conductivity measuring instrument has a rotary structure. Like the RNLY / DRY-300FG series cabinet thermal conductivity instrument, the double-plate thermal protection structure is used inside. It belongs to the steady-state temperature field measurement method and conforms to the national protection plate method. Thermal conductivity measurement standard GB / T10294-2008 (Determination of steady-state thermal resistance of insulation materials and related characteristics) and international standard ISO / DIS 8302-1991, also in line with GB / T3399-1982 (Test method for thermal conductivity of plastics-heat protection flat plate method ) And GB / T10801 (polystyrene foam for thermal insulation) national standards for the measurement of thermal conductivity.
The RNLY / DRY-300F series rotary thermal conductivity instrument adopts manual clamping of the test piece, but the repeatability and accuracy of the cabinet type thermal conductivity instrument are the same. In addition, because the sample loading device uses a rotating box structure, it is not only It is suitable for flat material measurement, and also for powder / granular material measurement. In addition, by selecting the pressure or thickness online measurement module, the online measurement of the pressure and thickness of the test piece can also be automatically achieved. The RNLY / DRY-300F series cabinet thermal conductivity meter can be widely used in thermal insulation and insulation material production enterprises, national and local quality inspection departments and units, universities and research institutes and other scientific research units.
