As you can see, the Guardian Avionics 451-201 is the most affordable option, but it also has the smallest operating range. The Midtronics 7200A and Aeromedix 9900 are both more expensive, but they have a wider operating range.
Here is a more detailed comparison of the three products:
- Guardian Avionics 451-201: This is the most basic option and is a good choice for small aircraft or helicopters. It has a small operating range of 0 to 500 PPM, but it is still effective at detecting carbon monoxide levels that can be harmful to pilots and passengers. It is also the most affordable option.
- Midtronics 7200A: This is a more advanced option that has a wider operating range of 0 to 1,000 PPM. It is also more sensitive to carbon monoxide levels, so it can detect lower levels of the gas. This makes it a good choice for larger aircraft or helicopters.
- Aeromedix 9900: This is the most expensive option, but it also has the widest operating range of 0 to 1,000 PPM. It is also very sensitive to carbon monoxide levels, so it can detect lower levels of the gas. It is a good choice for aircraft that operate in areas with high levels of carbon monoxide pollution.
Ultimately, the best carbon monoxide detector for you will depend on your specific needs and budget. If you are looking for the most affordable option, the Guardian Avionics 451-201 is a good choice. If you need a detector with a wider operating range or that is more sensitive to carbon monoxide levels, the Midtronics 7200A or Aeromedix 9900 are better options.
