Rugged, accurate and wireless
Designed for the field.
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.
Install anywhere – even one-handed.
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.
Three ways to use.

Specifications
The MG44 has a measuring range between 50-25,000 microns. Anything outside of that range will show the 4 dashes – – – -. The bar graph will show a wider range from deep vacuum up to atmosphere.

The moisture inside the system is still boiling off and is no longer being taken out or compensated for by the vacuum pump. The system will have to come to an equilibrium/ stabilizing.
Connect MG44 to empty recovery tank and pull down to 500 microns and isolate the pump from recovery tank and microns should rise slowly not immediately /fast rise.
Change the oil in the vacuum pump
Clean the sensor of the MG44 with rubbing alcohol. Do not stick anything into the sensor. Doing so will damage the sensor Check manual for details
Connect to the system. Techs typically prefer connecting to the Schrader Core Removal Tool (SCRT) or an unused service port
If using the Job Link mobile app as a display, add the MG44 to the tool manager in the app.
Microns being inaccurate is a sign of oil holding moisture either inside the block of the manifold, In the hoses or the oil in your vacuum pump needs to be changed.
Clean sensor periodically with rubbing alcohol.

First, the new wireless micron gauge MG44 works with SM380v/480v and not with previous generation wireless SMAN460. Existing SM380v/480v will require a firmware update in order to use with MG44. The firmware update instructions are available on the Fieldpiece website, go to https://www.fieldpiece.com/download-software-firmware-updates/. And production as of June 1, 2021 will include the newest firmware.
