Recently, Wuhan Jiayitong Technology Co., Ltd. officially launched the newly developed [Portable Zebeck Coefficient Tester PTM]. The tester is small and light, and can quickly measure the Seebeck coefficient of thermoelectric materials of different forms such as films and blocks. It can be used in the primary selection of thermoelectric materials, uniformity testing, high-flux experiments, thermoelectric teaching experience and other links related to thermoelectric materials. , It provides a more professional and portable new test option for the scientific research and industrialization of thermoelectric materials!

Portable Zebeck coefficient tester

This device is a portable thermoelectric parameter test product specially developed by Jiayitong Technology to realize the industrialization of my country's thermoelectric materials and create a "boutique project" under the suggestion of the elders in the field of thermoelectric materials in China!

1. Quick sample test

The test time is as low as 10s/time, and the test results are automatically presented, which greatly improves the team’s experimental efficiency.

2. Accurate test

Using stable and reliable method of measurement, simple operation, stable performance, accurate data (China Institute of Metrology takes NIST standard sample for comparison test, the test result error is within 7%)

3. Low sample requirements

Directly test the Seebeck coefficient of thermoelectric materials without special requirements on the shape of the sample.

4. Long battery life

The large-capacity battery can be used continuously throughout the day (more than 10h).

5.Small and safe

The equipment is small and light, easy to carry, and high safety performance

SEEBECK coefficient test results

[Portable Zebeck Coefficient Tester PTM] has been favored by customers once it was launched. At present, three scientific research units and enterprises, including the Institute of Chemistry of the Chinese Academy of Sciences, Xi'an Naisi Scientific Instrument Co., Ltd., and Guangdong Leizike Thermoelectric Engineering Technology Co., Ltd., have already purchased or are in the process of purchasing this equipment. In addition, there are more than ten universities, research institutes, and enterprises and institutions that are also very interested in buying this portable device.

This new product of Jiayitong was publicly exhibited for the first time at the Tenth China Thermoelectric Materials and Application Conference (May 6-9, 2018, Hangzhou, China), which attracted the attention of many teachers related to thermoelectric research. Some teachers directly brought the samples to the conference site for testing, and the test results were accurate and effective, and were highly praised by relevant teachers.

On-site sample testing at the conference

At the same time, Jiayitong Technology has always attached great importance to product technology research and development and upgrading. Although this [portable Zebeck coefficient tester PTM] has just been launched, its upgraded version is also under intense research and development, which will further improve the test performance of all aspects of the product, and provide more convenient and more convenient for customers engaged in the research of thermoelectric materials. A good product that is accurately tested.
