Brief introduction: DRX - II - JG laser thermal conductivity meter is to use a laser beam irradiation samples, sample temperature rise on the back is measured with infrared detector, to calculate the thermal diffusion coefficient of the sample. Has the characteristics of quick and convenient. The measurement of thermal diffusion coefficient is 0.025 px2 / SEC, and can measure the specific heat of sample, further calculation coefficient of thermal conductivity. Applied in the metal and alloy, diamond, ceramic, graphite and carbon fiber, fill plastic, polymer materials, such as testing. The main test instruments thin heat conductor, solid electrical insulating materials, granular materials, powder materials, the coefficient of thermal conductivity of coal. In line with the GJB 1201.1 91, ASTMD 1461 solid material, resin of thermal conductivity, thermal conductivity glass fiber, etc. Features: 1. A variety of mathematical model fitting and can perform a heat loss related correction; 2. To achieve a vacuum and protective atmosphere measurement two modes; 3. The multilayer analysis can be performed, and calculate the parameters such as thermal resistance, thermal diffusion rate. 4. Can connect the computer to realize automatic control, Chinese interface, operation, and automatically print test reports Technical parameters: Temperature: room temperature to 300 ℃; Coefficient of thermal conductivity test range: 0.1 ~ 2000 W/mK, 0.1 W/mK accuracy; Sample testing scope: square not less than 10 x 10 mm, round should be no less than 20, phi thickness 0.01 ~ 5 mm; Test sample types: solid block, low viscosity liquid, high viscosity, solid powder, viscosity and solid, elastic solid, film, etc all can adapt; Automatic sampler: no fewer than three samples;
