The MediaGauge Model MGA-9V is a NEMA 4X rated stand alone 9V battery operated multi-functional digital pressure gage. The MGA-9V digital pressure gage consists of a piezoresistive pressure sensing element, signal conditioning circuitry for temperature and calibration compensation, a 304L stainless steel pressure port and a LCD back lit display. The MGA-9V is a lower cost digital pressure gage in the MediaGauge family with accuracy of ±1.0 % full scale for dry air and non-corrosive gas applications only. The MediaGauge MGA-9V comes standard with a variety of keypad operated functions - multiple pressure unit display reading (PSI. BAR or MPA); memory storage of maximum peak pressure reading; and zero adjustment. The MGA-9V digital pressure gage has better accuracy, longer life and standard multiple functions which make it a better choice than mechanical pressure gages. These compact 2 J4 inch, robust gages measure pressures from 30 PSI to 300 PSI
