Could someone please post a picture of their gauge and splain to me how to use it?? I am looking to order one this evening or tomorrow. Any recommendations on which one to purchase??

As always, thanks in advance!!:cool:
 
I just put one up for sale... Old school style (less $$$), works perfectly!

Easy as can be to use, just need a small tube and whatever method necessary to connect to your particular stove. Since I could take my pressure measurements while the stove was cold, I used modeling clay to form a seal around the tube/hole to prevent any air leaks around the measurement hole. Ideally, you'd want a small fitting that would screw in and attache to the hose, but it's not rocket science.
 
Thanks guys...lbcynya,Why are you selling (dumb question, obviously you don't want it any more)?? Seems like a good price!

Really can't adjust draft (to any real extent) on my stove, so I really only need it once to see what my baseline was. So, might as well make room in the closet and let someone else use it...

I have Dwyer MARK 22 that bought in a yard sale for almost nothing. Brand new are as high as Ibcynya's. I use a rubber stopper with 1/8" brass tubing bought in ACE hardware to connect in the stove. I have to plug one of the holes for the air wash inlet and connect the meter in the other hole to get better readings. When the 25-PI is cold readings go to 0.3" and hot go to 0.13 - 0.15", anything below 0.10" means the stove or burn pot needs cleaning even with the flame looking good.

Here's a magnehelic from the Harman Pellet Training Handbook & some basic instructions on its usage...
