Starting to sell "Seebeck Coefficient / Electric Resistance Measuring System ZEM-5 series"
corresponding to the features of various kinds of thermoelectric materials

July 2, 2012 ULVAC-RIKO, Inc.

ULVAC-RIKO, Inc.(Head office: Yokohama, Kanagawa; President and CEO: Yoshikazu Ishii) has developed “Seebeck Coefficient / Electric Resistance Measuring System ZEM-5 series” specialized in each application and will start to sell from July.

We have developed and are now selling “Seebeck Coefficient / Electric Resistance Measuring System ZEM-3” corresponding to the performance evaluation of thermoelectric materials.
Recently, effectively using energy has been encouraged along with the emission reduction of CO2 . The requests for power saving have been increased and the developments of energy saving technique have been accelerated since last year’s East Japan earthquake.
Attentions to thermoelectric materials have been drawn as a maintenance free and a clean technology since they are converted to electricity from heat without any driving part.
As developments of thermoelectric materials have been advanced, the performance evaluation with high level for various kinds of materials has been pursued. We have developed “ZEM-5 series” specialized in the features of various kinds of materials such as high temperature materials, high resistance materials and thin films, and so on.. We have supplied thermoelectric materials evaluation system to respond to the detailed requirements of various kinds of materials.

“Seebeck Coefficient / Electric Resistance Measuring System ZEM-5 series” which we are ready to start to sell, specializes in the specification corresponding to features of various kinds of materials.
We adopted C type thermocouple with low reaction as Si series thermoelectric materials. We reviewed measurement system to measure higher resistance (Actual measurement:10MΩ) which are equal to that of oxide thermoelectric materials. We have developed optimization of sample assembly and measurement method to evaluate thin films (nano order), low-middle temperature type specialized in the needs of evaluation at close to room temperature and the evaluation of small sample with a few millimeter.
