Cheap but got the job done.
I had to buy a few different tubes and adapters to make this work on my furnace, but ones it was setup, I could get it dialed in and it worked well. Good cheap option to check furnace.

pas assez précis
une mesure sur une bouche d'aspiration de VMC n'est pas assez précise, il faudrait une échelle en Pa et non hPa mais ils sont tous pareils !!
