Overview

GEIGER CO Personal Carbon Monoxide Monitor by ThinAir

Much smaller, more responsive, USB rechargeable and more affordable than competitive models.

Geiger CO is a key fob-sized unit that provides real time aural alarm when carbon monoxide levels are dangerously high. The auto calibrating unit includes an aural alarm and a visual LED scale.

In contrast to competitive products, GEIGER CO is much smaller, more responsive and rechargeable. It is designed to run off of an internal USB rechargeable battery.

Geiger CO is designed to be attached to a keychain, but because of its small size, it can be hung anywhere, which makes it desirable for anyone who travels (for use in truck cabs or hotel rooms, for example). According to our market research, this is the smallest, most portable, most usable CO monitor available, and it is reasonably priced.

How To Use

  • Turn the unit on, unit will auto-calibrate every time
  • Unit monitors air
  • When CO levels rise, LEDs show change and alarm sounds
  • Power or charge via USB

Specifications

  • Size is 1.2 x 2.0 x 0.3" (3 x 5 x 0.75 cm)
  • Runs for up to 10 hours on a single charge
  • Detects Carbon Monoxide, sounds alarm at approximately 50 ppm
  • Shows at a glance CO strength through visual LED scale
  • LED scale is much easier to read in the dark than competitive products
  • Hangs anywhere using keychain attachment
  • Solid aluminum case (special early units ship with lightweight black nylon / carbon fiber)

Small and sensitive device. Alarm is loud enough to be heard with headphones on.

I bought my unit back early when it was offered only directly from the manufacturer. This detector is nothing short of fabulous. I fly in a rented Piper PA28-161 ( Warrior II) and the classic black bot panel mounted adhesive detector probably for all I know has not been changed since the plane was built in the early Reagan Administration. No one seems to know the installation date of the black dot detector, and the print has faded so badly that if any sort of date was ever marked, its been sun bleached to oblivion. Again, it is a rental at a flight school. I would recommend this unit particularly for renters. People who own their own plane perhaps can install more sophisticated panel mounted detectors. For scrub hobo renters like me, this unit is perfect. I have it on a lanyard along with my laminated checklists. The unit is also handy when at home or in hotels. Its extreme portability means it can be used in many places. The manufacturer of this device also has a lot of expertise in manufacturing light weight avionics for experimental aircraft. This unit is very rugged and well built. Two other posts have reported supposed premature alarms. Perhaps the units are indeed just doing their job and immediately signaling a 50ppm CO level, transient though it may be. Ive had my unit for about a year and it has gone off twice under circumstances that seemed reasonable. Again... highly recommended. especially for renters.

Nice and compact. Seems to work well, I tested near my ATV exhaust, no readings in my aircraft which is a good thing. The reason I only gave it four stars is it does not come with a charging cable and they failed to mention that in the description.

Okay, I hate giving less than stellar ratings but monitor falls a bit short.. Not by letting the gas get to you, but by freaking out when any CO even thinks about coming around or any volital organic compound. Its just too sensitive. I have worked inthe chemical industry for the past 30 years. If you have an alarm set point set too sensitive, it alarms too frequently and becomes a nuisance alarm. If you let it chrip on you learn to block it out theyou start to tune out other alarms. This sets up a bad normalized deviation where you start blocking out warning signs. Please figure out how to make it not so twitchy and it will be a great unit. Gonna head Back to my yellow 2year unit.

Case comes apart in your pocket. Nothing holds it together except the snug fit between the case and the cover. 6 months old and no external signs of abuse. The circuit board just falls right out. Not a good sign for an aviation safety device. Also did not come with a charging cord. Bought at the initial price of $99.99. Aviation is expensive...but come on boys, I expect better than that.

Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Is the alarm sound loud enough to be heard in a flying aircraft for a pilot wearing a noise cancelling headsets?

Per the manufacturer, there is no specific data that tells us yes or no. It will need to be tested in the specific environment.

Q: Does this unit display the level of CO in the cockpit? Are there any markings on LED scale or any digital display?

As the CO rises more LEDs will light up.

Q: Does the Geiger CO Carbon Monoxide detector only come in one color?

Yes, this is now available only in black. We used to ship the units out in orange, but due to supply issues on the orange material it was changed to black casing.
