The SSI Technologies MG-300-A-9V-R MediaGauge is a battery-powered digital pressure gauge with a 0–300 PSI range, designed to measure pressure in liquids and gases without requiring any external power supply or wiring. The part number decodes as follows: MG = MediaGauge, 300 = 300 PSI full-scale range, A = all-media (compatible with liquids and gases), 9V = 9-volt battery powered (9V Energizer battery included as shown in photos), R = bottom-mount 1/4 in NPT male process connection. The gauge features an LCD display with backlit readout, three front-panel pushbuttons (ON/UNIT/OFF, Backlight/Min-Max, and RESET/CLEAR), min/max pressure memory recall, and selectable pressure units. The wetted parts and process connection are stainless steel, making this gauge suitable for hydraulic systems, pneumatic circuits, water/fluid systems, and general industrial pressure testing.
