I'd love to if they weren't like $400

$100:

Carbon Monoxide Meter | Waterproof | USA NIST Calibration

A perfect CO meter for first responders. The CO detector is perfect for travel, camping, marine, RV, home, car, vehicle, automotive. A excellent carbon monoxide detector.

I get by with a $150 Sensorcon CO and one-gallon ziplocks.

What is your life worth to you? They are as low as $100.

Always bring your CO monitor and check every tank.

If the problem were compressor crankcase lubricant fumes getting into the compressed gas, would a CO detector have shown a problem?

If the problem were leaking piston rings and crankcase fumes getting into the compressed gas, would a CO detector have shown a problem?

Most likely. The products of combustion inside the cylinder include CO, and if the piston rings are leaking, it could allow products of combustion (including CO) to enter the compressed gas.

What combustion? I thought that the air compressors for SCUBA gas were electrically powered. At any rate I don't think that combustion and breathing gas compression can happen in the same cylinders.

Some are; many are combustion powered.

At any rate I don't think that combustion and breathing gas compression can happen in the same cylinders.

It's all too common as mentioned in my signature for years.

A source of CO in Electric driven compressors (besides intake air contamination) is when the compressor rings get hot or old and allow oil to enter the compression chamber and cause the oil to "flash" and produces CO. This is usually because of poor maintenance (clogged filters, old oil, worn rings...).

This one looks better, for scuba. More $$, though.
