CTA-3S Thermoelectric Material Testing System
Introduction:
The CTA-3S thermoelectric material testing system is an upgraded version of the CTA-3 system with more powerful hardware (data acquisition, transformer, power regulation module, temperature regulator and electromagnetic field shielding processing, temperature control method optimization, etc.), which improves the accuracy of temperature field control and the accuracy and repeatability of measurement data.
characteristic:
1. Advanced application temperature control technology, including advanced requirements such as temperature difference and measurement step
2. Free temperature rise/fall, precise temperature control program for data measurement during heating, constant temperature, and cooling processes
3. Thermocouple probes can be configured in K, S, or R types (without armor), which will not generate very large contact resistance
4. Automatic pressure safety protection design, imported US aerospace grade hardware configuration, ensuring that no explosion occurs during the testing process
5.The U-I curve is automatically scanned to calculate the appropriate current value, which can accurately measure conductivity; Will not cause errors on high resistance samples
6. Platinum large electrode design, which can fully contact the sample and obtain good conductivity testing for uneven samples
7.The spacing between thermocouples can be adjusted and fixed according to the sample size to meet different scientific research requirements
8. The temperature difference range of 0-80K can be freely set with temperature difference values and the number of temperature difference points
9. Light wave furnace heating technology, clean heating wit
hout contaminating samples and non-volatile, ensuring the safety and health of operators; Overall waterway design and gold plating treatment, no scale blockage problem, lifetime maintenance free. 10. Equipped with a vertical layout structure, upper and lower sample support clamps (sandwich), precise control of temperature difference
11. Standard imported advanced commercial current source (ADCMT), non circuit board integrated constant current source, to avoid thermal effects and inaccurate measurement caused by inaccurate output of small currents
