This little pressure gauge is something you'll keep in your cabinets for a quick digital readout. The gauge has a large backlit display so you can read your pressure at any time of the day. The metal head swivels, so it allows you to get into tough spots or get a better angle to read the display. The tire gauge is powered by two L1154F / LR44 button cell batteries & a large CR2032. I suggest picking up some extras so when it does die, you have batteries ready to go.
The digital gauge readout can read in multiple units:
PSI / Bar / kPa / kg/cm²
Specifications:
Calibration: 0-170 PSI / 0-12 Bar / 0-1200 kPa
Reading Resolution: 0.5 PSI / 0.05 Bar / 10 kPa
Accuracy: +/- 1 %
