The Snap-on Digital Tire Inflator, No. TPGDL2000, features 0 to 200 psi range and +/- 1 percent of full-scale accuracy. The inflator’s error-proof zero-out function calibrates the gauge to account for changes in temperature and ambient air pressure, ensuring an accurate reading. The tool is able to withstand daily, repeated use, and contaminants such as water, oil, or tire sealant. It has a user-selectable pressure scale (psi, bar, kgf/cm2, or kPa), field repairable/replaceable parts when damaged/worn, AAA batteries for easy replacement, and an auto-off feature to prolong batteries.
