Product Description

 Ultra-low Temperature Thermal Expansion Coefficient Tester Thermal dilatometer
1.Product introduction
This instrument is used to test the low-temperature linear expansion coefficient according to the standard "GJB1875-94 Test Method for Thermophysical Properties of Rigid Foam Plastics"; it is used to test the ultra-low temperature average linear expansion coefficient of various solid materials. The test method used is the ejector method, which uses (imported) high-precision micro-sensors to sense the deformation values of the samples at different temperatures. The computer technology is used to automatically complete the detection, control, calculation, printing and storage of the samples.

2. Sample size: less than 20×20×50mm, 3 samples can be tested at the same time;
3. High-precision micrometer sensor (imported) is used to sense the deformation value of the sample at different temperatures, with a range greater than 15mm, a resolution of 0.1um, and an accuracy of 0.2um.
4. Average linear expansion coefficient test range: 0.001~300.000×10-6/ºC
5. Test accuracy: 0.2%;
G: Air circulation method in the box: centrifugal fan forced circulation;
H: When heating up (the set temperature is positive), the temperature is not allowed to exceed 1ºC of the set value;
When cooling (the set temperature is negative), the temperature is not allowed to exceed -1ºC of the set value;
I: Heating time: within 60 minutes, from 0 to +300ºC;
Cooling time: within 40 minutes, from 0 to -190ºC;
6. The computer can collect and control three samples at the same time, and can also select some channels not to collect, and can enter sample information separately. Real-time data calculation, display expansion coefficient, volume expansion coefficient, linear expansion, rapid cooling expansion. Automatically calculate the compensation coefficient and automatically compensate, and can also be manually corrected (online). Automatically record, store (file name includes sample information), print data, and print temperature-expansion coefficient curve. The temperature interval can be set freely, with a minimum interval of 1°C.
