Product Description
XIANGKE ZRPY-DW (-196 ℃~+200 ℃) ultra-low temperature vertical expansion instrument ，Ultra low temperature thermal expansion coefficient tester
This instrument is suitable for measuring the volume changes (expansion and contraction) of metal materials, ceramics, glazes, refractory materials, as well as non-metallic materials such as rubber and plastics that occur with temperature changes between -196 ℃ and+200 ℃.
Instrument reference standards: GB/T1036-2008 Determination of Linear Expansion Coefficient of Plastics - Quartz Dilatometer Method, GB/T2572-2005 Test Method for Average Linear Expansion Coefficient of Fiber Reinforced Plastics, GB/T 20673-2006 Determination of Linear Expansion Coefficient of Rigid Cellular Plastics Below Ambient Temperature, etc.
Main technical parameters:
1. Adopting vertical and push rod type; The sample is easy to load and unload, avoiding the influence of the sample's own gravity on the testing.
2. Temperature range: -196 ℃ to+200 ℃ can be set, using liquid nitrogen system for refrigeration,
3. Voltage: AC 220V; Power: 1000W;
4. Strong compatibility with samples, capable of measuring the coefficient of expansion of glass rods, tubes, plates, and finished products. Sample size: diameter (5-10) x height 50mm or (5-10) x (5-10) x 50mm, square or circular. We can also customize other size specifications according to customer requirements;
5. The instrument can be connected to a computer for online display and printing of expansion curves, all raw data, Tf points, and calculation of line expansion coefficients and Tg points;
6. Temperature fluctuation in the refrigeration room: ≤± 1 ℃;
7. Temperature control accuracy: ± 1 ℃;
8. The measurement resolution is 0.1 micrometers, and the testing accuracy is ± a × 0.1 × 10-6K-1;
9. Test rack material: high-purity quartz.
Configuration: Includes one ZRPY-DW (-196 ℃~+200 ℃) ultra-low temperature vertical expansion instrument host (including liquid nitrogen temperature control device), one set of software, one liquid nitrogen tank, one quartz standard sample, one set of data cables, and one computer.
