LRH-ZD-300 Thermal Conductivity Tester Heat Protection Plate Method
1.Description:
This instrument is based on the principle of unidirectional stable
heat conduction. When the upper and lower surfaces of the sample
are at different stable temperatures, it measures the heat flow
through the effective heat transfer area of the sample, the
temperature difference between the two surfaces of the sample, and
the thickness, and calculates the thermal conductivity. It meets
the high-precision testing requirements of material testing
research departments for the thermal conductivity of materials.
2.Standard
GB/T3399 "Test Method for Thermal Conductivity of Plastics -
Thermal Shield Plate Method", GB/T3139-2005 (Test Method for
Thermal Conductivity of Fiber Reinforced Plastics) (Test Method for
Thermal Conductivity of Fiberglass Reinforced Plastics),
GB/10294-2008 "Determination of Steady-State Thermal Resistance and
Related Properties of Insulation Materials - Protective Heat Plate
Method", etc. The main tests include plastics, glass, fibers,
foams, insulation materials, etc. It is widely used in large and
medium-sized colleges, research institutions, quality inspection
departments and production plants for material analysis and
testing.
3.Feature:
1. Automatic thickness measurement: Utilizing high-precision
displacement sensors for measurement and connecting to a computer
for automatic thickness measurement, thereby reducing human error.
2. Automatic Pressurization System: The system automatically
applies pressure. It enables the measurement of thermal
conductivity under various pressure conditions. This method is more
scientific, data-driven, and has higher repeatability compared to
manual pressure application.
3. Various measurement types: In addition to measuring hard plates,
by selecting various accessories from the company, it is possible
to measure a wide range of special materials. For example: granular
materials, loose materials, soil, etc.
