Mitech XXQ-2505 Portable X-Ray

Rp123

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.

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.
