Seebeck Coefficient / Electric Resistance Measurement System ZEM 3 series Simultaneously measures the Seebeck coefficient and electric conductivity of thermoelectric materials. Based on requests from both domestic and international academic societies and customers, this system features our easy to use, high-precision measurement techniques. Complies with JIS standards for thermoelectric material Seebeck coefficient measurement equipment.



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

A patent and a standard

Thermoelectric power JIS R 1650-1
Resistivity JIS R 1650-2


Special Features / Further Applications


  • Uses an Infrared Gold Image Furnace with superior temperature controllability and a micro heater for temperature difference control
  • Measurements are computer-controlled, which allows for measurements at each temperature difference at specified temperatures and automatic measurements to eliminate dark electromotive force
  • Ohmic contact self-check function (V-I plot) is standard
