About Shearwater Petrel 2 EXT OC/CC W/ Fischer Port Dive
Rugged and Reliable. The Petrel 2 Fischer features all the modes of the Petrel 2 and incorporates a fischer connector for integration into rebreathers for primary or redundant PPO2 monitoring with full decompression. The Petrel2-EXT includes a Fischer 103 I/O port used for external PO2 monitoring of up to three oxygen sensors in a rebreather loop. Once the Petrel2- EXT is plugged in to the sensor cable via the Fischer 103A connector and calibrated it uses the PPO2 input from the sensors to determine the system average PPO2 used for decompression calculations and CNS tracking. A voting algorithm is used to decide which of the three sensors are likely to be correct. If a sensor matches either of the other two sensors within 20%, it passes voting.
