Xiangtan Xiangke ZRPY-III-DWLow-Temperature Vertical ExpansimeterThermal Expansion Coefficient Measurement Instrument
This instrument is suitable for measuring the volume changes (expansion and contraction) of metals, ceramics, glazes, refractory materials, plastics, and other non-metallic materials, as they change with temperature from low temperatures (-60℃) to 200℃.
Instrument Reference Standards: GB/T 1036-2008 "Determination of Linear Coefficient of Thermal Expansion of Plastics - Quartz Dilatometer Method", GB/T 2572-2005 Test Method for Average Linear Coefficient of Thermal Expansion of Fiber Reinforced Plastics.
Main Technical Parameters:
1. Vertical and push rod types are used to eliminate the influence of the sample's own weight, particularly suitable for the testing of large-sized samples.
2. Temperature Range: -30～100℃ or -60～200℃ (either specification available)
3. Tolerance range for deformation: ±1.5mm.
4. Displacement sensor sensitivity: 0.1 um, automatic range correction.
5. Temperature Control Accuracy: ±1℃
6. Automatically calculates the expansion coefficient, volume expansion, and linear expansion.
7. Automatically calculates and compensates for compensation coefficients, with the option for manual adjustment.
8. Sample Sizes: Available in specifications such as Φ(6~10)×H(30~50)mm, Φ(6~25)×H(50~100)mm, Φ(6~50)×H(50~100)mm, etc., with square or round samples accepted; also customizable to other sizes according to customer requirements.
9. Power: 220V, 2KW
10. Automatic temperature control, recording, storage, and data printing, with printing of temperature-expansion coefficient curves. All test operations are completed through a computer interface, offering convenient and easy-to-learn operation with a full software package.
11. Refrigeration Method: Compression refrigeration for -30～100℃ specifications.
- Specifications ranging from -60 to 200°C utilize liquid nitrogen cooling.
Note: AdditionalLow-Temperature Vertical ExpanderProducts in the 196～200℃ specification.
Instrumentation Configuration:
- Specification: -30 to 100℃ range includes one vertical expansion instrument main unit, one software set, one data cable and communication interface set, one quartz standard sample, and one desktop computer (can be provided by the buyer).
- Specifications: -60～200℃ model includes one vertical expansion instrument unit, one software set, one data cable and communication interface set, one quartz standard sample, one self-pressurized liquid nitrogen tank, and one desktop computer (available for customer's self-provisioning).
Note: Optional bidirectional detection available upon customer request, allowing for simultaneous measurement of expansion in both directions.
