Temperature Rise Tester for Transformer Live Winding

Product No: LSTMR-103

  • Specifications

  • The LSTMR-103 live winding temperature rise tester is a specialized instrument focused on measuring winding temperature rise, used to assess the core performance of small-power motors and electronic transformers. The instrument accurately measures the cold and hot resistance of the windings, calculating the temperature rise data. It supports simultaneous live testing of single or two windings to meet various testing needs. Equipped with a color LCD display, the data is presented clearly and intuitively. It features automatic range switching to ensure measurement stability and repeatability. Furthermore, it supports multiple communication interfaces and USB flash drive storage, facilitating convenient data reading, saving, and traceability, providing reliable testing support for product development, quality control, and life testing.
