Compared my manometer to a draft analyzer today

The maint crew at work has a very expensive digital draft analyzer that I compared my dwyer 460 against. They use it for reading the furnaces and boilers for the foundry so it is very tight spec and calibrated frequently. So we drilled two hole next to eachother in a boiler flue and set the two next to eachother. The draft analyzer was 1.5 inches of water lower than mine. This was significant to me because I also compared my manometer to my step dads as he has the same koker and manometer as I and his was also 1.5 lower than mine. So im assuming my gauge is off. Jus though I would share.

did you let the red oil acculimate in room temp., when I start the boiler up,the oil will have a different reading for a day after,can't remember if higher or lower,but it certinly wasn't 1.5 different

We checked a few before we started using them and found them to be pretty close. I would contact Dwyer and see what they say they may have had a bad batch or just yours. They seem like a pretty good company to deal with.
