As you can see, the Extech CO240 is a basic CO2 monitor with a good accuracy and measuring range. It also has data logging capabilities and audible and visual alarms. However, it is not the most sensitive CO2 monitor on the market, and its battery life is not the best.

The Dräger X-act 8000 is a more sensitive CO2 monitor with a wider measuring range. It also has a faster response time and longer battery life. However, it is more expensive than the Extech CO240.

The Amprobe CO260 is the least expensive CO2 monitor on this list. It has a good accuracy and measuring range, but it does not have data logging capabilities or visual alarms.

Ultimately, the best CO2 monitor for you will depend on your individual needs and budget. If you are looking for a basic CO2 monitor with good accuracy and a reasonable price, the Extech CO240 is a good option. If you need a more sensitive CO2 monitor with a wider measuring range and longer battery life, the Dräger X-act 8000 is a better choice. And if you are on a budget, the Amprobe CO260 is a good option.
