Heating up to 3000K within one second!
This system measures thermophysical properties by applying current directly to a sample to heat up to higher temperature within one second. Measurable standard properties are electrical resistivity, total emissivity, specific heat capacity, thermal expansion rate and thermal diffusivity.
Features
- Applying current directly to a sample can make it possible to heat up to more than 2000℃ quickly.
- Heat-resistant materials used in high temperature of more than 2000℃ can be measured.
- More than two properties can be measured simultaneously.
Electrical resistivity, Total emissivity*1, Specific heat capacity, Thermal expansion rate*2, Thermal diffusivity*2 - Temperatrure controllability: within 1% (at 2800℃)
- 1Easy installation with power supply 100V/15A and no need of cooling mechanisms like cooling water
- High energy-saving is expected because measurement can be done in a short time.
*1 Hemispherical total emissivity (compliant with JIS-R1693-3)
*2 Optional
