RD-2505TH Portable Industrial X-ray Flaw Detector 250kV 5mA 40mm Steel Penetration

RD-2505TH Portable Industrial X-ray Flaw Detector

The RD-2505TH is a portable, SF6 gas-insulated industrial X-ray radiography system built for field and workshop non-destructive testing (NDT). It pairs a 130–250 kVp constant-potential generator with the MIXN series intelligent controller, delivering 40 mm A3 steel penetration in a 5-minute exposure at 600 mm focal distance. The complete set weighs only 35 kg (26 kg tube head + 9 kg controller), so one technician can carry and position it for weld, casting and pressure-vessel inspection.

Key Features

• MIXN intelligent control system – high-intensity anti-interference circuitry with modular main board and air-duct cooling for stable continuous operation.
• SF6 gas insulation, anode-grounded design – hermetically sealed aluminium tube head with multi-blade aluminium heat sink and forced-air fan cooling.
• Soft start and gradual shutdown – protects the X-ray tube and high-voltage transformer, extending generator service life.
• Fully automatic conditioning mode – automatically steps kV up and backs off on discharge, with automatic rest cycles and cumulative exposure-time tracking.
• Industrial-grade stepless rotary knobs – rapid, repeatable kV and time setting; last-used parameters are retained in memory after power-off.
• Safety door interlock terminals – connects to lead-shielded room door control; “SD” alarm protects personnel.
• Comprehensive protection – mA under/over-range, real-time voltage protection, discharge detection, over-temperature (“HT”) shutdown.
• Field-ready construction – rubber shock-absorbing corner guards, hinged top cover with latching mechanism, end rings for vertical or horizontal positioning.
• Delayed exposure & remote status lights – freely adjustable start delay and side-mounted indicators for safe, distanced monitoring.

FAQ

Why Asian Terminal Users Choose This Model

Single-phase 220 V input matches workshop and site power in most Asian markets, the 35 kg set is transportable by one technician, automatic conditioning removes the need for a trained high-voltage operator, and the ±1% mA stability keeps film density repeatable across long inspection shifts. Spare parts, tubes and controllers are stocked for a 10-year service window.
