Features
● Quick sample test: The test time is as low as 6s/time, and the test results are automatically presented, which greatly improves the team's experimental efficiency.
● Convenient operation: use two hot and cold probe pens to directly touch thermoelectric material samples of different forms, the system automatically calculates, and the test results are quickly presented.
● Low sample requirements: Directly test the Seebeck coefficient of thermoelectric materials, and there are no special restrictions on the shape and structure of the sample.
Applications
● Material preliminary selection: rapid screening of thermoelectric material samples such as films and blocks, improves the efficiency of the preliminary selection process, avoids useless experiments, and greatly saves experimental costs
● Uniformity test: it can quickly detect the uniformity of one or more different forms of thermoelectric materials, and make a preliminary quantitative evaluation of the internal and external uniformity of the material
● Quality inspection: It is perfectly suitable for the quality inspection of thermoelectric materials, and can intuitively and quickly judge whether the relevant thermoelectric materials meet the corresponding quality standards
● Undergraduate teaching: Perfectly suitable for the teaching of various thermoelectric materials related principles and experimental explanations at the undergraduate level
