By the way, had another 'incident'.

 

Two nights ago my wife was stripping an old piece of furniture on the porch.  Looked like rain so I told her to put it in the basement.  

Had forgotten that I relinquished my old Nighthawk down there.  After about an hour I hear something alarming in the basement.  Sure enough the Nighthawk was going off.

 

Took a CO Experts monitor down.....nothing.

 

Take care,

R.

 

Thank You, .... once again this PROVES that "Building" a Good C  O Sensor REQUIRES a Good "Stacking / Filtering Process", of a Sensor designed "Specifically" for Carbon Monoxide, ..... NOT a "Multi-Gas Sensor".
