The simple way of invasive measurements

The RTI MAS-1 is an invasive probe for the measurement of mA and mAs. Together with Piranha or the Cobia SENSE, direct reading of mA and mAs, as well as waveform, are obtained. The probe connects to the mAs socket in the X-ray generator and to the multimeter.

It can be used to measure tube current for both radiographic and fluoroscopic exposures.
