Like every piece of Fieldpiece hardware, the Wireless Vacuum Gauge (MG44) is built to make your work easier. It helps eliminate misleading measurements by allowing you to connect it at the system port - even those awkward, hard-to-reach spots. It's also housed in a rugged impact- and weather-resistant case. The new, smaller cylindrical shape of the Wireless Vacuum Gauge, its no-slip grip, and the addition of a reversible angled coupler-mean the MG44 is easy to manipulate and install in the toughest spots.
