Temperature Rise Test

A temperature rise tester is a test device used to measure the temperature changes of motors, transformers, cables, switches and other equipment during operation. Its main purpose is to evaluate the heat dissipation performance of the product, the heat resistance of the material and whether it complies with relevant safety standards.

High-precision Measurement
The thermoelectric potential coefficient of the K-type thermocouple used in the temperature rise tester is about 41 µV/°C, which means that for every 1°C increase, a voltage change of 41 microvolts will be generated. This enables our tester to effectively detect subtle fluctuations in temperature, with a measurement accuracy of up to ±0.1°C, far exceeding the industry's common ±0.5°C standard.

Multi-channel Synchronous Measurement
Compared to ordinary products with only 8-16 measurement channels, our temperature rise tester is equipped with 32 independent measurement channels, which can simultaneously monitor the temperature changes of up to 32 parts such as coils, cores, and fuel tanks, greatly improving the test efficiency. In contrast, ordinary equipment may require multiple tests to complete the same work.

Large Data Storage Space

Our temperature rise tester has a built-in 8GB large-capacity storage, which is far more than the 1-2GB storage space commonly found in similar products. It can record continuous measurement data for up to 24 hours in real time. In contrast, many similar products often need to export data or replace storage media regularly during long-term testing, which not only increases the complexity of operation, but also increases the risk of data loss.
