Product Introduction

----------------------------------------------------------------------

The MINI-MAX bolt stress tester adopts advanced ultrasonic reflection technology, which can accurately and quickly measure the duration and elongation of bolt tightening, and further convert them into load, stress, and strain. It has the characteristics of easy use, intuitive display, and portability. The MINI-MAX bolt stress tester is widely used in fields such as aerospace, satellite manufacturing, power equipment, construction bridges, and petrochemicals due to its unique concept, powerful functions, and accurate measurements.
