Product Description
Xiangke DRPL-III-300 Fully Automatic Thermal Conductivity Tester (Guarded Hot Plate Method)
I. Overview
Fully Automatic Thermal Conductivity Tester (Guarded Hot Plate Method) It adopts the popular hot plate method to detect thermal conductivity and thermal resistance. It is equipped with a computer to achieve fully automatic detection and generate experimental reports. It is suitable for testing the thermal conductivity of low-conductivity materials such as insulation materials and refractory materials. With the addition of sample frames, it can also test powder materials. It is widely used in colleges and universities, research institutes, quality inspection departments, and factories and mines.
This instrument refers to the following standards: JIS-1412-2 Determination of thermal resistance and thermal conductivity of thermal insulation materials, GB/T10295-2008, ISO 8301:1991 (Determination of steady-state thermal resistance and related properties of thermal insulation materials - Guarded hot plate method) and ASTM C518-04 Test method for determining steady-state heat flux and heat transfer properties using a heat flow meter.
II. System Composition:
1. Hot surface heater, high-precision programmable temperature control, hot surface temperature measurement resolution is 0.1℃,
2. The cold surface uses a constant temperature water bath for temperature control, with fluctuations less than 0.05 degrees, and a cold surface temperature measurement resolution of 0.01℃.
3. Equipped with a protective control device to effectively eliminate the influence of the environment on the test and ensure the accuracy and repeatability of the test.
4. Equipped with automatic pressurization and automatic thickness measurement functions, it can detect the thermal conductivity and thermal resistance under different pressures.
