Does anyone have any experience with this CO detector for Scuba?

Carbon Monoxide Super-Meter | 0.1 ppm | Scuba | USA NIST Calibration

Low level carbon monoxide meter which is the most sensitive detector on the market providing 0.1ppm of carbon monoxide gas resolution. low level CO detector, low level carbon monoxide detector, low level CO alarm, low level co monitor, carbon monoxide meter.

I had thought the Palm was the one to get, but then came across this, and was intrigued, especially as it is a lot less expensive. However, I am also concerned as it is a lot less expensive and I wonder if I would get what I paid for...

So figured it made sense to ask around. Thanks for any experiences shared!

Yes, I have one, and it has been reliable so far. It takes about 60 seconds to power up. The highest reading I’ve observed in any of my fills was 0.2 ppm. When I first received the unit, I experimented with it and was able to get readings as high as 10 ppm when positioned close to an exhaust source.


Additionally, the company was highly responsive when I reached out with questions about the optimal flow rate for accurate measurements.

Good review on its big brother.

Like everything I write, this is long and detailed, and you may not need much of this detail. I use a CO monitor both for continuous CO monitoring of my compressor, as well as ad-hoc checking of tank fills I get elsewhere. This is divided into sections so that you can skip the sections you don't care about, or skip to the next post to get to the details of the unit -- of *course* this is more than 10,000 characters...

Compressor CO Monitoring​

For just about as long as I've had a compressor, I've had Carbon Monoxide (CO) monitoring. I use a Nitrox stick, and I wanted a way...

We have one and I agree with the comments above about both the product and the company. Measuring CO is slower than measuring O2 (for Nitrox) but it does work and is rugged enough for dive travel.

Thanks for the responses, I think I'll give it a try.

@NachoMan, curious about the optimal flowrate. I have a flow limiter I use for my Nitrox analyzer, do you use a similar device to test for CO? If so, does that work ok?

Thanks again!

Dr. Koz at FORENSICS DETECTORS recommends a flow rate between 0.1 and 0.3 LPM. Your unit should include a dome attachment with a restricted orifice that easily snaps on, helping to regulate pressure from the cylinder and preventing sensor damage. I use a quick-release connector with an output flow of 0.2 LPM—the same setup I use with my Divesoft He/O2 analyzer.

Perfect, I have a flow limiter I bought for my Nitrox analyzer that is .2, so should work well.

Thanks again!
