words, we want to monitor Carbon Monoxide level in the house before it’s reached 70 ppm to catch the problem early.
With a digital display we can see the level of carbon monoxide, the trend and the pattern. It’s one story if CO is always present in the house at some level, and completely different story if it goes from 0 to 100 ppm in 30 min.
It helps to have an alarm with memory. We can check what’s happened when we were away.
AC power supply is preferred. Avoid detectors running on batteries, unless there is no AC outlet around.
To sum up. When choosing an alarm, watch for approval, digital display and monitoring capabilities, AC power supply, memory.
