Digital High-Pressure Gauge, SMG series are professionally digital gauges used for maintaining, monitoring and evacuating refrigeration systems and charging refrigerants. The gauges can measure system pressure and display various parameters such as the evaporation temperature of the corresponding refrigerant. They have a backlight, auto-off, unit switch, over-range alarm, and other functions.
