“do you think the CO monitor is working properly?”
___________________
Jeff,
Good question. Have I seen a “calibration test result”
for this particular unit? No.
The first time I turned it on was in my hanger without the heaters
on. It read zero. I then started all the diesel heater and placed
the meter about 10 foot in front. I expected to find some CO – but the
meter stayed on zero? Then took it in “the tent” and fired up
the 4 propane catalytic heaters. Waited a few minutes, again expecting to
have some CO – but the meter stayed on zero? Hmmm – same question
– is this thing working properly? I then started up the propane
turbo heater and immediately got an indication of CO – it quickly went up
to 17 PPM and settled at 13. After 10 minutes I turned the heater off and
the meter very quickly returned to zero. Lots of ventilation. I
left the meter on during the day and moved it around the hanger – reading
stayed at zero.
My trust was still in question so to verify my earlier test I
started the propane turbo again – same results.
At the end of the day I started my vehicle and went back into the
hanger to gather my stuff and the meter started squawking at me. It was
reading in the 30’s. I was surprised by that but it gave me an
indication of its sensitivity. I left it on, put it and my stuff in the
car. The meter went to zero.
Repeated the procedure the next day – same results.
Tested it at home in a closed garage. Started the car (different
vehicle) and the reading quickly went to 57 and after a couple of minutes
settled on 53. Turned the car off and the meter slowly returned to zero
as the air changes occurred.
So – I’ll continue to use the monitor for
reference. I’ll continue to “make some CO” now and then
to see the meter move off the zero reading. I’ll continue to
monitor other indications for the presence of CO.
Yes – I do think the CO monitor is working properly.
