The R22D or R22DHO have molex kk 3 terminal contacts. These respond to partial pressure of O2 so the response varies in
proportion to (O2 concentration)*(pressure). The diving ones have a high rejection to condensation and surface contamination.

Lifetime 21% O2 @ STP should be good for 3 years. Somewhat less at ~1ATM partial pressure O2 with ambient pressures in excess of
15ATM!

Generally the R22D response from new is 9mV to 11mV in air after allowing a few hours to waken up if straight out of the
package.

Subject: [TN] Oxygen sensor

Can anyone recommend a good oxygen sensor that can be used to verify the level of a nitrogen blanket? I am looking for one that
can be used to verify the oxygen percentage inside of the reflow oven, or on a rework station, or within a nitrogen box used for
storage of components.
Thanks for any responses.
