This is a neat little analog style of tire pressure gauge that comes in a nice metal storage case that you can throw in your glove box. These are so small and light, I plan on having one in the glove box of each of my cars, so if I really need to check pressure, I can do so without worrying about a dead battery in a digital pressure gauge. The gauge has a black cap on the end which doubles as a valve stem core remover for when you need to remove air really fast. The angled head is designed to take a measurement at a 90-degree angle.
The gauge can read in PSI & Bar units of measurement.
Calibration: 6-50 PSI in 1 lb units 0.5-3.4 Bar in 0.1 Bar units
