CO problem???

Yes the tech from the oil co. did use a wet tester. All his readings were fine to him (draft was neg. CO2 was 9.7%
The original test at instalation was done digital (Testo) and read co at 673ppm
The inspector for NSTAR is the one who read 2000ppm.
I don't know whose right here and they all claim they are, that's my dilema.

I recently posted this message elsewhere and wanted to get other responses.I recently had a hot water boiler installed, (oil).
The unit installed and then checked for efficiency by a licensed oil burner tech, and everything checked out fine.
Now the problem, An independent vendor for NSTAR Electric came by to do there inspection and tells us the co level in the flue has maxed out their meter at over 2000ppm. The drafty is ok, it is going up the chimney and there isn't any levels in the occuppied space in the area of the boiler.
My tech says there reading aren't correct and would come out to verify but couldn't make it right away. My wife, being nervous called our oil co. and they sent a tech out to do a test.
He stated that the draft was neg. the co was 9.7 % not ppm ( which he says oil burner aren't read in ppm).
I'm getting mixed information on this and I'm hoping someone could clear this up for me. They are using 2 different testing instruments The tech using a bachrach liquid test and the inspector a digital test instrument.
Sorry for the lenghthy explanation, I look forward to anyone's answers. Reply Edit

Thank you for your reply. What range would be acceptable for flue gas? This way I'll have an idea when they test it.
