CDX-III portable AC magnetic particle flaw detector with interchangeable probes for surface cracks in welds and steel parts.
Overview
The CDX-III is a portable AC magnetic-particle flaw detector using the external-magnetisation method, consisting of a control unit and interchangeable probes. One host accepts four probe types: A (horseshoe / fillet-weld), D (electromagnetic yoke), E (cross/rotating-field) and O (ring), covering welds, flat and irregular surfaces and shaft/pipe work for surface and near-surface crack inspection. Magnetisation and applied magnetic particles form indications at leakage fields. It is compact, light, and jointed/roller-equipped for field use; widely used in pressure vessels, pipelines, steel structures, bridges and castings.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Portable and lightweight design for on-site field testing
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the CDX-III Portable Magnetic Particle Flaw Detector comply with?
A1: The CDX-III Portable Magnetic Particle Flaw Detector is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the CDX-III Portable Magnetic Particle Flaw Detector be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
