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.
Applications
Carbon materials, Metal materials and Space development etc.Features
- Applying current directly to a sample can make it possible to heat up to more than 2000°C quickly.
- Heat-resistant materials used in high temperature of more than 2000°C 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°C)
- Easy 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.
