What Our Clients Say
Testimonials
R&D Manager
Emma
"We needed a fast and accurate way to check core loss in prototype motor stators. This instrument delivers stable readings with minimal drift. The software export function is very handy for our internal reports. Customer support responded to our questions within 24 hours."
Production Supervisor
Carlos Mendez
"Our operators learned to use it in less than an hour. The calibration routine is straightforward, and the probe connection is robust. "
Quality Engineer
Sophia
"We’ve been using this iron loss tester for six months on our electrical steel production line. The measurement repeatability is excellent, and the setup is intuitive. The single-sheet tester option saved us a lot of time compared to the traditional Epstein frame. Highly recommended."
Procurement & QA
Anna Schmidt
"We test every batch of silicon steel sheets from our suppliers. This iron loss tester gives us confidence to accept or reject materials on the spot. The carrying case and well-packed accessories also made international shipping worry-free. A reliable tool we use daily."

Not necessarily. The user interface is designed for intuitive operation with on‑screen prompts. However, we provide a detailed user manual and video tutorial (available on YouTube). For bulk orders, we also offer free online training via Zoom/Teams.
Yes. You can freely set the test frequency to either 50 Hz or 60 Hz (as well as other custom frequencies) through the control panel. This makes it compatible with global industrial standards.
