Need to buy a draft meter.

[Tristan]

I am installing my Harman XXV. I am also going to be using the Outside Air Kit wall thimble. From what i've been reading so far, it sounds like i need to purchase a device to measure the draft. Can someone please point me towards the right direction to purchase such a device. Can you please provide me any neccessary links etc. Thank you so much in advance.

Dig around ebay also - search Draft Gauge or BACHARACH or Magnehelic, although you will have to get a mag which is very low on the scale like .02 to .10


this is the one - 70 bucks new:
2000-00 Differential pressure gage, range 0-0.25" w.c., minor divisions .005, calibrated for vertical scale position.
