ZRPY-1600 Horizontal Vacuum Expansion Coefficient Tester Introduction: This instrument is mainly used to measure the thermal expansion coefficient of solid materials such as ceramics and refractory materials, especially corundum refractory materials, glass and graphite materials, as well as shell and core materials for precision casting. This provides modern means for factories and technical inspection departments to test the quality of ceramic and refractory products, as well as for scientific research and teaching units. This instrument complies with GB/T3810.8-2016 for the determination of linear thermal expansion of ceramic tiles, as well as GB/T16920-1997 for the determination of average linear thermal expansion coefficient of glass, and 4-2003 for the determination of thermal expansion coefficient of graphite electrodes, GB/T 7320-2008 "Test Method for Thermal Expansion of Refractory Products". Compared with other expansion coefficient measuring instruments, the ZRPY fully automatic intelligent series is currently a high-precision instrument leading in the industry in terms of expansion coefficient measurement, control, and data processing. Technical parameters: 1. Maximum temperature: Room temperature~1600 ℃. 2. Heating rate: adjustable from 0 to 20 degrees per minute, temperature controlled by computer program. 3. The computer automatically calculates the coefficient of expansion, volumetric expansion, linear expansion, and rapid thermal expansion. 4. Automatically calculate compensation coefficient and compensate automatically, or manually correct (online). 5. Automatically record, store, and print data, print temperature expansion coefficient curve with a minimum spacing of 1 ℃ 6. Expansion measurement range: 0~3mm 7. Resolution of measurement expansion value: 0.1um, automatic calibration range 8. Sample range: Ф6-10mm， 50mm in length, cylindrical or square can be used 10. System measurement error: ± 0.1~0.5% 11. Maximum power consumption: 2.5KW 12. Power supply voltage: 220V ± 10%, 50HZ 13. The instrument is equipped with a standard computer interface that can be connected to a general-purpose computer. All experimental operations are completed through the computer interface, making it easy to learn and provide a complete set of software. 14. Vacuum degree ≥ -0.09Mpa
