Mitech XXQ-2505 Portable X-Ray

Mitech XXQ-2505 Portable X-Ray Flaw Detector

Product Overview

The Mitech XXQ-2505 is a portable X-ray flaw detector developed for high-precision non-destructive testing (NDT) in industrial environments. It identifies internal defects—such as cracks, voids, and inclusions—by measuring X-ray absorption differences in materials of varying thickness and density. Its inflatable tube design, lightweight construction, and user-friendly interface make it particularly well-suited for on-site inspections, even in challenging or high-altitude conditions.

The system captures high-resolution images on specialized X-ray film, offering clear visual representations of internal flaws. These images can be preserved for long-term analysis and are not affected by surface roughness or grain structure, making this unit highly versatile across different materials and applications.

Functions and Applications

Commonly used in:

• Shipbuilding

• Machinery manufacturing

• Aerospace and railways

• Pressure vessel and boiler inspection

• Oil, gas, and chemical plants

• Military and defense applications

Suitable for detecting internal flaws in:

• Weld seams

• Metal castings

• Structural components

Working Principle

The XXQ-2505 generates X-rays through a high-voltage circuit powered by a silicon-controlled rectifier and thyristor chopper. These X-rays penetrate the test object and are absorbed at different rates depending on the material’s thickness and composition. The unabsorbed rays are captured on X-ray film, which, once developed, displays the defect locations and their characteristics.

Key Features

• microcomputer control system for consistent and intelligent operation

• compact and lightweight for easy transport and use in the field

• automatic overtemperature protection to preserve tube integrity

• stable current regulation using pulse frequency control

• continuously adjustable tube voltage for diverse testing needs

• anti-interference circuit to reduce electrical noise and signal distortion

• full safety system with fault code display

• strict 1:1 work-to-rest duty cycle for optimal thermal management

• delayed high-voltage activation for operator safety

• separate high-voltage and control units for increased reliability

• adaptable to generator-based and unstable power supply conditions

Specifications

• operating temperature: -25°C to 40°C

• relative humidity: ≤ 85%

• safe working pressure: 0.35 – 0.50 MPa

• package dimensions: 40.5 × 40 × 72.5 cm and 47 × 47 × 33 cm

• total weight: 45–80 kg

• do not operate below 0.35 MPa

Operation Guidelines

• power on the unit; the display shows “HH” and the fan activates

• after 15 seconds, set exposure time using the rotary knob

• preheat the tube to stabilize vacuum conditions

• adjust tube voltage (kV) to match inspection material

• press “HV” to begin exposure; countdown begins automatically

• once complete, the system shuts down high voltage and enters a cooling period before standby

Delay Start Setup:

• press and hold “HV” for 3 seconds to set delay (0.1–5 minutes)

• indicators flash and buzzer sounds

• system starts automatically when delay ends

To cancel delay:

• restart the unit, or

• press “HV” again to show “00” and release

Safety Notes

• always use 2 mm lead plate or equivalent shielding during operation

• maintain a 20-meter safety radius if shielding is not available

• ensure internal pressure is at least 0.35 MPa

• verify proper grounding of the controller unit

• keep cables and connectors clean and secure

• do not power off the unit during rest cycles to allow fan cooling

• minor voltage fluctuations may trigger safety shutdowns; this is not a malfunction

The Mitech XXQ-2505 is an effective, field-ready solution for internal defect detection in critical industrial components, combining safety, clarity, and operational flexibility in one compact device.
