The simple way of invasive measurements

The MAS-1 Probe is an invasive probe for the measurement of mA and mAs. Together with Piranha or Cobia Sense, direct reading of mA and mAs, as well as waveform, are obtained. The MAS-1 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 fluoroscopic and radiographic exposures.

RTI MAS-1 Probe with Piranha & Cobia Sense

The MAS-1 Probe supports the  Automatic Detector Identification system. When connected, the Piranha or Cobia automatically identifies the probe and makes all necessary adjustments without any need for interaction from the user. The ADI system also gives full interchangeability of probes between different Piranha or Cobia systems.
