Don't throw away your old sensors!

Galvanic sensors are made of acid and heavy metals, throwing them might bring those materials where they don't belong.

CCR application requires the sensors to not current limit before they reach PO2=1.6 while analyzers requires the sensors to reach PO2=1.0 therefore they can be reused. 

Dive Hard O2 Analyzer is the perfect companion for anyone who can source those CCR sensors for free, it accepts both Molex and Coax type sensors.
