Seebeck Coefficient / Electric Resistance Measurement System ZEM-5 series

A series corresponding to special specifications for the properties of various thermoelectric materials and thin films
A higher level evaluation for various kinds of materials has been required along with the development of thermoelectric materials. This system “Seebeck Coefficient / Electric Resistance Measuring System ZEM-5 series” is specialized in the features of various kinds of materials such as high temperature, high resistance and thin film, etc. and a performance evaluation system to correspond to various kinds of needs.


Evaluate the thermoelectric properties of a wide variety of materials including semiconductors, ceramics, and metals


  • A series corresponding to special specifications for the characteristics of various thermoelectric materials and thin films
  • A type C thermocouple is used for the temperature detection sensor, making this system optimal for evaluating Si-based thermoelectric materials (SiGe, MgSi, others) (model HT)
  • V/I plot that self-diagnoses the ohmic contact is standard
  • Measurement of high temperature up to 1200°C (model HT)
  • Measurement of high resistance of maximum 10 MΩ (model HR)
  • Measurement of materials formed as a film on substrates (model TF)
  • Measurement of low temperature from -150°C to 200°C (model LT)
