HZ-7039P Multi-functional Thermal Conductivity Tester Heat Flowmeter Method

This instrument mainly tests the thermal resistance of thin thermal conductor, thermal conductive silicon film, thermal conductive resin, beryllium oxide porcelain, alumina porcelain and other fine materials, and the contact thermal resistance at the solid interface and the thermal conductivity of materials.Testing material is generally solid sheet, such as adding a frame can also detect the powder state material and paste material.
Reference standard: MIL-I-49456A (insulating sheet, thermal conductive resin, thermal conductive glass fiber enhancement); GB 5598-85 (determination method of thermal conductivity of beryllium oxide porcelain); ASTM-D5470-12 (test standard for thin thermal conductive solid electric insulation materials), etc.
The instrument has automatic pressure pressure, automatic thickness measurement, the full computer automatic measurement and control function.

HZ-7039P instrument is developed based on HZ-7039O instrument with the following characteristics:

1. A protective heat device is added around the test rod in the test head (this device can thermal protect the test sample), which expands the test temperature range of the instrument and reduces the impact of ambient temperature on the test.

2. The temperature difference thermocouple of heat flow test is added to the test rod in the test head to improve the resolution, accuracy and repeatability of heat flow test.

3. The compensation for the thermocouple cold end of the ice-water mixture is cancelled, which simplifies the operation and facilitates the use.

4. Experimental methods such as "aging reliability test", "high thermal conductivity material test" and "inter-sample contact thermal resistance test" were added. HZ-7039O and HZ-7039P Multi-functional Thermal Conductivity Tester can be widely used in material thermal analysis and testing in colleges and universities, scientific research units, quality inspection departments and production plants.
