Description

Drawell Transient Plane Heat Source Method Thermal Conductivity Meter BXT-DRS

Product overview

The BXT-DRS rapid thermal conductivity tester is a thermal conductivity tester developed using transient planar heat source technology (TPS), which can be used to test the thermal conductivity of various materials. The transient plane heat source method is one of the medium-sized methods for studying the heat conduction performance, which brings the measurement technology to a whole new level. The ability to quickly and accurately measure thermal conductivity when researching materials provides great convenience for enterprise quality monitoring, material production, and laboratory research. The instrument is easy to operate, the method is simple and easy to understand, and it will not cause damage to the tested sample.

The Drawell Transient Plane Heat Source Method Thermal Conductivity Meter BXT-DRS supports research, pharmaceutical, environmental, food, industrial, and quality-control laboratories. Scientific China provides model selection, configuration review, export coordination, and formal quotations.

Key features

Transient Planar Heat Source Technology (TPS) is a new method for measuring thermal conductivity, developed by Professor Silas Gustafsson of Chalmer University of Technology in Sweden on the basis of the hot wire method. The principle of measuring the thermophysical properties of materials is based on the transient temperature response generated by a step-heated disc-shaped heat source in an infinite medium. A flat probe is made of thermal resistance material, which serves as a heat source and temperature sensor…
The thermal resistance coefficient of the alloy is a linear relationship between temperature and resistance, that is, the heat loss can be known by understanding the change of resistance, which reflects the thermal conductivity of the sample. The probe of this method is a continuous double helix structure sheet formed after etching treatment of a conductive alloy. The outer layer is a double-layer insulating protective layer with a very thin thickness. It makes the probe have a certain mechanical strength and…
During the test, the probe is placed in the middle of the sample for testing. When the current passes through the probe, a certain temperature rise is generated, and the generated heat is simultaneously diffused to the samples on both sides of the probe. The speed of thermal diffusion depends on the thermal conductivity of the material. By recording the temperature and the response time of the probe, the thermal conductivity can be directly obtained from the mathematical model.
Fast and accurate: 5-160S can complete the test.
Non-destructive testing: the sample is not damaged and can be reused.
Simple sample preparation: no special requirements for sample size.
A wide range of test objects: block solids, granular solids, liquids, powders, colloids, pastes can be tested.
High flexibility: independent sample holder, detachable probe, flexible testing.
User-friendly page, easy to operate: LCD touch screen display, easy to operate, easy tounderstand.
Instrument reference standard: ISO 22007-2 2008
The test range is wide and the test performance is stable, which is at a level among similar domestic instruments;
Direct measurement, the test time can be set about 5-160s, which can quickly and accurately measure the thermal conductivity, saving a lot of time;
It will not be affected by contact thermal resistance like the static method;
No special sample preparation is required, and there are no special requirements for the shape of the sample. The bulk solid only needs a relatively smooth sample surface and the length and width are at least twice the diameter of the probe;
