Tells you the waterlift and mercury lift at machine or end of hose or the wand. Attach to your vac hose for quick reading.
Works on 1 1/2″ hose and 2″ hose. Great way to check if your machine is pulling correct amount of lift.
This gauge is 30HG gauge = 408″ water lift (1HG = 13.6″ lift)
Sir Clean Miami –
This gauge is indispensable to check the working conditions of your machines.

It’s nice to know how much vacuum you have at the end of a long run and if you have to throw a booster in place haven’t had to use a booster yet but it’s a great gauge
