Rigaku Radioflex RF-2522CP 220kV Constant Potential Radiographic Generator Set

Radiographic Inspection System for Non-Destructive Testing (NDT)

Rigaku have recently launched their first constant potential portable x-ray inspection instruments. These compliment the Rigaku’s EGM2 series pulsed instruments. The all new constant potential range of instruments are competitively priced and enter the market with an unmatched price, performance ratio, backed up by Rigaku’s quality, reliability and after sales service.

Compact and Lightweight

The RF-2522CP is a 220kV constant potential radiographic generator set that includes a raft of features to help NDT professionals increase their workload by working more efficiently. More specifically, the new system is amongst the smallest and lightest constant potential units on the market making it more portable and easier to transport and set up. The x-ray generator tips the scales at a mere 20.4kg and the controller a lithe 10.kg, making the unit easy to handle and manoeuvre in the field. The designers have been able to achieve these light weight components using Rigaku’s unique high voltage technology.

Efficient Operation

Unlike many of its competitors, it can also operate continuously for 30 minutes at 100% duty cycle enabling data to be collected faster. The RF-2522CP achieves all this at a paltry 1.5kVA, making it one of the most energy efficient systems on the market.


Suitable for most applications, the RF-2522CP can see through 50mm of steel. However, for those needing more power, Rigaku have also released the RF-3530CP, the big brother to the RF-2522CP. It is amongst the most powerful on the market, able to penetrate 70mm of steel.
