The Piranha MAS-1 Probe is an invasive probe for the measurement of mA (tube current) and mAs. The probe simply connects to the mAs socket of the X-ray generator. Together with the Piranha direct reading of mA and mAs as well as waveform are obtained. The Piranha mAs-1 probe measured from 0.1 mA to 3000 mA.
The Piranha MAS-1 Probe can be used to measure tube current both for fluoroscopy and radiography exposures. The probe has a built-in low-pass filter with user-selectable bandwidth of 5 or 500 Hz. The probe accepts a floating input range of ±90 V relative to ground.
The MAS-1 Probe supports the Piranha ADI (automatic detector identification) system. All information about the probe is stored in a memory inside the probe. When connected, the Piranha automatically identifies the probe and makes all necessary adjustments without any need for interaction from the user. The Piranha ADI system also gives full interchangeability of probes between different Piranha systems using the same type of probes.
