Should I test every scuba tank for carbon monoxide?

Testing scuba tanks for carbon monoxide is completely at the discretion of the diver. No standard for testing tanks currently exists. Owning a carbon monoxide detector is a good idea for dive shops, and companies that do dive tours for others. Recreational divers may also wish to test for CO, but again, it's at their sole discretion.

How often does my dive tank Carbon Monoxide Detector need calibration?

For the Sensorcon Inspector, we recommend every 180 days. However, this also depends on how precise you need your readings to be. Given the current US "standard" for carbon monoxide in dive tanks of 10 PPM, even a 40% error range in concentration should be good enough to know if there's a carbon monoxide issue with your dive air.

Day 0: +/- 10%
Day 180: +/- 20%
1 year: +/- 30%
2 year: +/- 40%
3 year: +/- 60%

So after 2 years without calibration, the 10 PPM threshold would register somewhere between 6 PPM and 14 PPM. In both cases, further investigation is warranted.
