Quality Carbon Monoxide Detectors for Scuba Cylinders

[4togrfr]

However Forensics Detectors makes 2 sensors, one with 1 ppm precision and one with 0.1 ppm. Price of the more precise one is double. I wonder if the sensor is indeed more sensitive or if it’s just marketing.

I was wondering the same. I am buying a CO meter before heading off on out next trip to Indo this Spring and planned on picking up the Forensic’s scuba specific one (.1ppm resolution), but I’m also considering one off Amazon for around $40 with 1ppm resolution. As mentioned by Tmassey, this really just needs to be a pass/fail detector. Any detectable level of CO and the tank should be rejected. My remaining question is with the lower resolution, does the Forensics meter have a lower detection threshold than the cheaper generic ones on Amazon?

Check that the ones on Amazon will read below 10ppm, that seems to be the lower range for most and twice what is considered safe.
