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 off 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 read out can read in multiple units: PSI / Bar / kPa / kg/cm²
