They make several units, but the basic $139 CO Inspector is really handy for travelers & divers. Get it now for $111 using PROMO CODE: SPRING2018 at check-out. See Portable Carbon Monoxide Detector Meter (CO Inspector)
This unit weighs just 4 ounces, it's rugged & waterproof on the surface, and it includes a handy steel alligator clip with lanyard loop. I carry mine everywhere, great for monitoring vehicle safety, and you know that hotel rooms almost never have CO alarms.
It can further be used to test tank gases as it's accurate to 1 ppm in low range, +/- 10% at ambient conditions, plus +/- 10% after six months since calibration. Some divers have rigged low flow 1/4" hoses, but I just use freezer quality gallon ziplocks to trap tank air. Warning: crack tank valve first, then place bag over. I once sent a unit flying overboard by cracking a tank with the bag already placed! Fortunately it trapped enough air to float until we could turn the boat and retrieve it.
My current unit is nearly 2 years old (they replaced my first one after a mailing error when I sent it in for calibration in 2016), but I figure it's still accurate enough, with less than 2 ppm variance. I leave it on all of the time but they will replace the battery when I send it in for calibration this summer.
The 20% discount does not apply to calibration services, but at $39 every other year - I am not bothered.
