I got a carbon monoxide detector, which reads 0 ppm. It has a feature that allows you to check the highest level within the past 24 hours, which also is 0 ppm. Is this normal? I thought there might be one or two ppm in the house.
Answer
It can read it. But f you want to know if it is working then it will either need to be calibrated by a professional (cheaper to buy a new one), or quick gut check take it to the hood of an 80% gas HW heater. It should give you some reading and I usually see above 9 when around a water heater.

What level of carbon monoxide is dangerous?

My NIGHTHAWK carbon monoxide detector is reading 9...I did just cook a turkey, but...help?
Answer
That detector is reading in parts per million (ppm). 9 ppm is basically harmless. OSHA allows workers to be exposed to 50 ppm. 100ppm is considered fatal. They set those detectors very low to give you plenty of time to correct a problem.
What JB said about opening a window is a good idea.
