Top 10 Best Vacuum Gauge In [2022]

[MATERIAL]: Housing Material: Stainless Steel; Connection: Copper Alloy; Movement: Copper Alloy; Bourdon Tube: Copper Alloy; Window: Polycarbonate
[SIZE]: Dial Size: 2″; Thread:1/4″ MNPT
[ACCURACY AND SCALE]: +/- 3% ; PSI and Bar
[Liquid Filling]: Glycerin
[APPLICATION]: Normal Ambient Temp.:-4F to +140F (-20C to +60C)；It is suitable for places with severe vibration，the damping liquid (glycerin) can resist the vibration of working environment and reduce the pulsating effect of medium pressure.
