everybody knows

Jiayitong has a small device called

[Portable Zebeck coefficient tester PTM]

It is a new product launched in May this year to test the Seebeck coefficient of the material

Has been on the market for nearly half a year

[Attention immediately after listing] Jiayitong’s portable Zebeck coefficient tester PTM debuted at the 10th China Thermoelectric Materials and Application Conference (May 6-9, 2018, Hangzhou, China), attracting many thermoelectrics at the conference Researching the attention of related teachers, one after another came forward to consult and test samples.

[Widely concerned] Less than two months after the listing, this small device has received widespread attention from relevant universities, research institutes and thermoelectric material companies-crowds and crowds, email and telephone consultation, agent application, free trial , Order to buy.... An endless stream! At the same time, enthusiastic teachers put forward many valuable opinions on the problem.

Customer feedback summary graph

[Continuously polished and improved] An ordinary portable device has been widely concerned by the market! This makes Jiayitong engineers both excited and stressed. In order to make a good product that satisfies customers, we are determined to improve and upgrade the product-collect customer opinions, formulate feasible improvement plans, work overtime, rectification, modified testing and verification, customer trials and collecting feedback, once again Improvement... keeps on looping back and forth.

List of improved features (partial)

[Quick test] The newly upgraded PTM-3 has a measured boot time as low as 4.8 S/time. After the engine is fully warmed up, the measured time for a standard sample of nickel tape is 6 S/time (the test time for different material samples may be slightly different) , Can greatly improve the team’s experimental efficiency.

[Easy operation] Whether it is easy to get started or not is one of the most concerned issues of the sample tester. PTM is easy to operate. Use two hot and cold probes to directly touch the thermoelectric material samples of different forms, and the system can automatically calculate and quickly display the test results. Easy to learn and easy to use, the teacher no longer has to worry about you not knowing how to operate the instrument.

[Sample requirements are low] Regardless of whether it is a block, fiber or film thermoelectric material sample, the Seebeck coefficient can be tested directly, and there is no special restriction on the shape and structure of the sample.

Product diagram

[Different versions, different features] The new generation of portable Zebeck coefficient tester PTM is divided into two versions: PTM-3, which is positioned in the scientific research-grade thermoelectric material market. It has the highest configuration and is important in test error, measuring range, sample resistance range, etc. On the one hand, it can meet the scientific research requirements of thermoelectric materials; PTM-2, positioned in the thermoelectric-related enterprises and teaching instrument market, is more cost-effective. It can not only meet the needs of thermoelectric material enterprises for quality inspection and production spot checks, but also is an excellent teaching instrument. It can be perfectly suitable for the teaching of all kinds of thermoelectric materials related principle teaching and experimental explanation at the undergraduate level.

[Partners] Currently, there are more than ten customers in use: Tsinghua University, Beihang University, Institute of Chemistry, Chinese Academy of Sciences, Wuhan University, Guangdong Institute of Rare Metals, Guangdong Leizike, Hebei University, Inner Mongolia University of Technology, etc. Thermoelectric materials key scientific research universities, research institutes and thermoelectric materials companies.
