Gauge details: Analog style, 2 1/2' size, 0 - 30 psi range, 1/2 lb increments, 1/2 lb / 2% accuracy. The swivel ball chuck holds pressure, and it has a GID (Glow - In - The - Dark) feature.

Using this tire gauge is easy. First, locate the tire valve stem. Then, attach the swivel ball chuck of the gauge firmly to the valve stem. You'll be able to read the tire pressure on the 2 1/2' Glow - In - The - Dark face clearly. If the pressure is too high, you can use the high - flow release button to bleed some air. When not in use, keep the gauge in a dry place to prevent damage to the internal gauge damper. Try not to bend the ultra - flexible 17' hose sharply as it may affect its performance. Periodically check the accuracy of the gauge, and if you notice any significant deviation, it might be time to replace it.
