The Fieldpiece MG44 digital vacuum gauge is a professional measuring instrument for accurately checking vacuum levels during installation and maintenance work on air conditioning, heat pumps, and refrigeration systems.
The vacuum gauge has a measuring range of 50 to 25,000 microns and provides an accurate measurement of the vacuum during the evacuation of refrigeration circuits. This allows installers to verify that the desired vacuum level is reached before filling a system with refrigerant.
An important advantage of the MG44 is the wireless connection via the Fieldpiece Job Link System . This allows measurements to be monitored remotely via a compatible smartphone or tablet. The wireless range is up to 305 meters in clear line of sight . Obstacles and environmental factors can affect this range.
The vacuum gauge offers three ways to read measurement data : directly on the built-in LCD display, via the Job Link app, or via a compatible Fieldpiece SMAN digital manifold.
The LCD display with blue backlight ensures that measured values remain clearly visible even at poorly lit work locations.
The meter features a 1/4 inch SAE male connector , allowing the instrument to be connected directly to a suitable system port. This makes it possible to measure the vacuum as close to the installation as possible.
The MG44 supports various units of measurement, including micron, Pascal, mbar, mTorr, and Torr . This allows measured values to be displayed in the unit that best suits the work or the user's preference.
At a temperature of 25°C, the specified accuracy is ±(5% of the reading + 5 microns) within the range of 50 to 1,000 microns.
Thanks to the IP54 protection class , the device is protected against harmful amounts of dust and splashing water. The robust design makes the instrument suitable for daily professional use.
The vacuum gauge operates on 2 AA alkaline batteries and has a battery life of approximately 40 hours . The automatic shutdown after the default 15 minutes helps limit battery consumption.
Weighing only 300 grams , the MG44 is easy to transport during service and maintenance work.
This digital vacuum gauge is a practical tool for HVAC installers who want to perform accurate vacuum measurements and monitor them remotely.
