Feature: 1. Our tire pressure gauge supports up to 200PSI, and built‑in 4 different units for your convenience: PSI, BAR, KG /CM², KPA, and high accuracy within ±1 PSI. 2. Use this digital tire inflation meter to calibrate the pressure easily, it can display the test value of 2‑3s, and the measurement range is 3‑200PSI/14BAR/14Kgf/cm^2. 3. Clear LCD display is easy to read, the design with LED lighting makes it more convenient for you to use at night, and the bright backlit display makes it possible to read data clearly in the dark. 4. Deflation and inflation.
