CLA-L/MThermal Diffusion Measurement System
Introduction:
At a certain temperature controlled by the furnace body, a laser source emits light pulses to uniformly irradiate the lower surface of the sample, heating the sample uniformly. The corresponding temperature rise process on the upper surface of the sample is continuously measured by an infrared detector to obtain the relationship curve between temperature rise and time. The mathematical model calculates and corrects the theoretical curve and the experimental temperature rise curve to measure the thermal diffusion coefficient of the sample. The thermal conductivity of the sample is automatically calculated according to the following formula.
characteristic:
1.Advanced high-power laser: laser source adjustable parameters; The laser import mode adopts a direct built-in sample below to avoid thermal loss errors in the fiber import mode; The safety level of the laser has reached the highest level (Class 1), and no special safety measures are required during operation;
2.Detector class: InSb/MCT (imported customized)
3.Multi sample measurement bracket: Built in automatic system, 3 sample measurements, saving users time and work intensity;
4.Small volume furnace body technology: ensuring temperature uniformity and durability of the furnace body, without water leakage and furnace body lifting problems;
5.Compact design, can be operated and tested on a desktop, saving laboratory space;
6.Accessories such as radial anisotropy thermal conductivity and high-temperature molten liquid sample measurement can be configured;
7.Accurate finite element pulse correction;
8.Contains various mathematical calculation models;
9.Software automatically optimizes measurement parameters;
10.Multi layer composite materials or multi-layer composite coatings, conducting multi-level measurement and analysis;
