1 Introduction

MUT500B is a portable, fully digital deviceultrasonic flaw detectorIt can quickly, conveniently, without damage, and accurately detect, locate, evaluate, and diagnose various defects (cracks, inclusions, pores, etc.) inside the workpiece. It can be used in both laboratories and engineering sites. This instrument can be widely used in manufacturing, steel metallurgy, metal processing industry, chemical industry and other fields that require defect detection and quality control. It is also widely used in in-service safety inspection and life assessment in aerospace, railway transportation, boiler pressure vessel and other fields.

2 Functional Features

Instrument characteristics

Full Chinese display, master-slave menu, and designed with shortcut buttons and digital shuttle wheels, easy to operate and technologically advanced.

AT5100divided intoTFT（TFTFull color type) andEL（ELTwo sub models of high brightness type.

TFT adopts a fully digital true color LCD display, which can select background color, waveform color, and menu item color according to the environment, and the LCD brightness can be freely set;ELAdopting high brightness, wide temperature range, and military gradeELThe display screen can work under strong outdoor light, and the LCD brightness can also be freely set.

The high-performance security battery module is easy to disassemble and can be independently charged offline. The large capacity high-performance lithium-ion battery module extends the continuous working time of the instrument to more than eight hours; The instrument is easy to carry and can be held with one hand, durable and leading the industry trend.
