O2 analyizer

[JohnN]

I’ve pretty much given up on getting another CooTwo to replace mine with a failed motherboard

Is there an analyzer out there with a replaceable O2 sensor?

This is one of them

Palm D Oxygen Analyzer

The Analytical Industries Palm D Oxygen Analyzer is ergonomically designed to fit in the palm of your hand and is the most cost effective and reliable analyzer available for validating oxygen content of Air and Nitrox diving gases in scuba cylinders.

I think they all have a replaceable O2 sensor. At least they should be. The O2 sensors have a finite life, so should be replaceable. What varies is generally the specific type of sensor used.
