Elitech SMG-1L Refrigeration HVAC Digital Pressure Gauge Single Manifold Gauge

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.

LCD Screen& Blue Backlight Display

The pressure gauge's digital backlight display allows you to readout easily even in the night.
Partition display for different measurements, direct readings for all measurements.
Adjustable backlight off time: 3s,4s,5s,10s,15s or always on
Selectable auto off time: 10min (default), 20min,30min,40min or disable
