Wireless Vacuum Gauge
Rugged, accurate and wireless.
- 300m wireless range;
- 60 bar overpressure;
- Three ways to view measurements: Job Link® app, Digital Manifold, and the MG44 screen.
Our Wireless Vacuum Gauge gives you accurate and fast measurements as a stand-alone tool, and performs at a high level in combination with the other Job Link® tools as well.
Where to buy
Overview
Three reasons why you need our MG44 Wireless Vacuum Gauge
1. Wireless and fast
With a 300m wireless range, the MG44’s measurements can be read anywhere on site. Simply connect the tool to your Job Link® app or Digital Manifold and you will be able to access all your MG44’s accurate measurements in real time.
2. Built-in protection
With a 60 bar overpressure on the vacuum gauge, you no longer have to worry about damaging the vacuum sensor. The built-in overpressure ensures that the sensor can take up to 60 bar overpressure while the vacuum gauge still remains highly-accurate and robust.
3. Three ways to use
While you’re performing a vacuum, the MG44 ensures that you can monitor the vacuum progress through the Job Link® app or the Digital Manifold from up to 300 meters away. No need to guess what the measurements are, just look it up in real time!

Frequently asked questions
Can I connect the MG44 to the SMAN digital manifold?
Yes, the MG44 connects to our SM380/SM480. SM380/SM480 prior to production as of June 1, 2021 will require a firmware update in order to connect the MG44. The firmware update instructions are available on the Fieldpiece website, go to https://www.fieldpiece.com/download-software-firmware-updates/. Production after June 1, 2021 will include the newest firmware and does not require an update.
How can I read the measurements on the MG44?
There are three ways to view the measurements. ......................................................................................................................................................................................................................................................................................................................................................

Why is my vacuum pressure inaccurate?
Vacuum pressure being inaccurate is a sign of oil holding moisture either inside the sensor compartment or in the hose that the MG44 is connected to. The oil in your vacuum pump may also need to be changed.
Clean sensor periodically with rubbing alcohol.
How to clean/maintain my MG44?
Clean the sensor of the MG44 with rubbing alcohol. Do not stick anything into the sensor. Doing so will damage the sensor. Check the user manual for details.
Where is the best location to put the MG44 for most accurate vacuum pressure reading?
Ideally it is best to connect the MG44 to the furthest point in the system (away from the vacuum pump).
Why will my MG44 show vacuum pressure when directly hooked up to pump but not when I am pulling on a system?
Evacuation takes time. You are pulling a vacuum in a larger volume (Refrigeration system/AC system + vacuum pump) compared to just a vacuum pump. Check that there are no leaks in your hoses, change the oil of the vacuum pump, and perform a triple evacuation if there is an indication of a lot of moisture in the system.
How do I check if my MG44 is leaking or not?
Connect MG44 to empty recovery tank and using a vacuum pump pull down to 500 microns and isolate the pump from recovery tank. Microns should rise slowly and stabilize and not immediately rise.
Why does my vacuum pressure jump up when I turn off my vacuum pump?
The moisture inside the system is still boiling off and is no longer being taken out or compensated for by the vacuum pump. Allow sufficient time (this will depend on the volume of the system) for stabilization.
Why does my MG44 read – – – – ?
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.
What is the wireless range?
300 meters line of sight.
What is the maximum overpressure on the MG44?
The maximum overpressure for the MG44 is 60 bar (870psig)
Can my tool connect wirelessly to the manifold?
Yes, you can connect your tool to the manifold.
