Fieldpiece MG44 is a wireless micron vacuum gauge for HVAC/R service that provides direct system-port micron readings and remote monitoring via the Job Link app. The MG44 measures from 50 to 25,000 microns with 1-micron resolution, displays readings on a backlit dot-matrix LCD, and transmits over 2.4 GHz to 1000 ft line-of-sight. It runs on 2 x AA alkaline batteries and features an IP54 weather-resistant, over-molded housing.
Measurement range 50 to 25,000 microns with 1-micron resolution and accuracy ±(5% of reading + 5 microns) (50â2000 microns).
Wireless monitoring via 2.4 GHz radio up to 1000 ft line-of-sight; compatible with Job Link app (BLE 4.0) and Fieldpiece SMAN manifolds.
Reversible 1/4 in SAE male 45 Deg coupler with Schrader depressors, backlit LCD (rate, bar graph, rate meter), IP54 water resistance, ~40 hours battery life (2 x AA).
