As you can see, the Guardian Avionics 451-201 is a very compact and lightweight CO detector that is designed to fit in a small instrument position. It has a sensitive sensor that can detect CO levels as low as 50 PPM, and it provides both audible and visual alarms when CO levels reach dangerous levels. The 451-201 is FAA NORSEE certified, so it can be installed in most certified aircraft.

The Midtronics 5010D is another compact and lightweight CO detector that is FAA NORSEE certified. It has a slightly wider temperature range than the 451-201, and it also has a built-in test button. However, the 5010D does not have an external mounting bracket, so it must be mounted directly in the instrument panel.

The Atlantic Systems 9000-2 is the smallest and lightest CO detector in this comparison. It is also the most affordable, but it does not have a temperature compensating circuit. This means that the alarm threshold may drift slightly as the temperature changes.

Ultimately, the best CO detector for you will depend on your individual needs and preferences. If you are looking for a compact and lightweight detector with a sensitive sensor and audible and visual alarms, then the Guardian Avionics 451-201 is a great option. If you need a detector with a wider temperature range or a built-in test button, then the Midtronics 5010D is a good choice. And if you are looking for the most affordable option, then the Atlantic Systems 9000-2 is a good value.

Guardian Avionics 451-201 Pros/Cons and My Thought

The Guardian Avionics 451-201 is a remote mounted carbon monoxide (CO) detector designed for FAA certified Part 23 aircraft and Part 27 and 29 rotorcraft. It is a compact and lightweight unit that is easy to install and use.

Pros:

• Small and lightweight. The 451-201 is only 4.0 ounces and measures 3.35 x 2.25 x 1.50 inches. This makes it easy to fit behind an instrument panel and takes up very little space.
• Easy to install. The 451-201 can be installed in about 2-4 hours by a qualified technician. The installation instructions are clear and easy to follow.
• Accurate CO detection. The 451-201 has a sensitive CO sensor that can detect levels as low as 50 parts per million (PPM). This gives pilots plenty of warning time to take action if CO levels start to rise.
• Loud audible alarm. The 451-201 has a loud 85db audible alarm that will sound when CO levels reach dangerous levels. This will alert pilots to the problem so they can take action to protect themselves and their passengers.
• Built-in temperature compensation. The 451-201 has a built-in temperature compensation circuit that ensures that it will accurately detect CO levels regardless of the ambient temperature.

Cons:

• No visual alarm. The 451-201 does not have a visual alarm, so pilots will only be alerted to CO problems by the audible alarm. This could be a problem for pilots who are hard of hearing.
• Requires an annunciator/alert light. The 451-201 requires the installation of an annunciator/alert light in the cockpit. This adds to the cost of installation and takes up additional space.
• Not TSO certified. The 451-201 is not TSO certified, which means that it is not approved for use in all aircraft. However, it is approved for use under the Non-Required Safety Enhancing Equipment (NORSEE) authorization.

User reviews:

Positive reviews:

• "This CO detector is a great addition to my aircraft. It is small, lightweight, and easy to install. The audible alarm is loud and clear, and I have peace of mind knowing that it will alert me to CO problems."
• "I was worried about CO poisoning in my aircraft, but this detector has put my mind at ease. It is accurate and reliable, and I would highly recommend it to other pilots."

Negative reviews:

• "I wish the 451-201 had a visual alarm as well as an audible alarm. It would be nice to be able to see the CO levels as well as hear the alarm."
• "I was disappointed that the 451-201 is not TSO certified. I would feel more confident if it was approved for use in all aircraft."

My thoughts:

The Guardian Avionics 451-201 is a good CO detector for aircraft. It is small, lightweight, easy to install, and accurate. However, it does not have a visual alarm and is not TSO certified. These are some drawbacks, but overall I think the 451-201 is a good option for pilots who are looking for a CO detector for their aircraft.

I would recommend the 451-201 to pilots who are looking for a small, lightweight, and accurate CO detector. However, I would also recommend that they consider a TSO certified CO detector if they are concerned about the safety of their aircraft.
