The 10 Best Carbon Monoxide Detectors For Cars
Editor's Notes
November 11, 2020:
Most of the devices on our list are continuous CO detectors, meaning they will test levels in real time and alert you when specific PPMs have been reached. However, we did include a few models that are for occasional use only. The Pyle Handheld, the GXG 1987, and the Klein ET110 are all CO meters that will test for levels when manually activated to do so. These options can be quite handy, particularly if you only need occasional checks. Unlike the other models on our list, however, they will not automatically test levels continuously, which means they will not alert you to any environmental changes.
If you plan to take your detector with you to job sites or unpredictable environments, you’ll want a wearable, long-lasting device. The Sensorcon Certified is made for industrial use and features a belt clip, waterproof exterior, and long battery life. Another on-the-go option is the recently added Gzair SA103, which offers a similar waterproof design and extended battery life. It features a keyring connector and holds up to rough conditions.
If you like the idea of a multi-functional device, the Fasohere 3.0 is a good choice. It doubles as a fast-charging station, and is tough enough to break glass in an emergency. However, the ultimate all-in-one item on our list is the newly added Lomak Canary, which crams six tools into one package. It allows you to monitor CO levels, while providing other emergency tools, like a seat-belt cutter and flashlight.
In terms of travel-friendly options, all of the models on our list are easy to carry, do not require instillation, and can tuck away in a car. That being said, it’s worth noting a couple other features convenient for portability. The UEi Test Instrument CO71A is the lightest choice listed, weighing only .3 ounces, making it a good toss-it-your-bag choice. If you want easy accessibility, the Toxin Sensors CM-2000 comes with an attached sun-visor clip, while the Forensics Detectors Meter includes a stick-on holder.
We removed the outdated, previously listed Quantum Eye Multi-Level. We also removed the Sunnec Alarm because it is not meant for car use or travel.

Selected portable models that can be used in a variety of vehicles, including cars, trucks, airplanes, and boats. For those seeking continuous monitoring, added the Forensics Detectors Meter and Toxin Sensors CM-2000; for passive, selected the budget-friendly ASA Detector and Quantum Eye Multi-Level. Did not add home models due to their mounting requirements and differing sensitivity, with the exception of the Sunnec Alarm, which could be useful for those who sleep in vehicles, such as RVers and van dwellers.
