Feature: 1. The tire pressure gauge supports up to 300PSI, and has 4 convertible units: PSI, BAR, KG /CM², KPA, and the accuracy is within ±1 PSI. 2. The digital tire inflation meter is easy to calibrate the pressure, can display the test value of 2‑3s, and the measurement range is 3‑300PSI/14BAR/14Kgf/cm^2. 3. Deflation and inflation. The bleed valve can be used to vent when the tire pressure is extremely high; when the pressure is too low, connect an air compressor (NOT included) and press the inflation button to inflate. 4. The clear LCD display is easy to read, and the bright backlit display makes it possible to read data clearly in the dark. 5. If there is no operation within 15 seconds, the tire pressure gauge will automatically turn off to save battery power. 6. Widely applicable and can be used in bicycles, motorcycles, cars, small and medium passenger trucks, small and medium passenger cars, etc. Specification: Item Type: Digital Tire Inflator Gauge Material: Aluminum alloy + copper + rubber high pressure pipe Display Mode: LCD digital display Pressure Unit: Four units can be switched, PSI, KPa, Bar, Kgf/cm^2 Measuring Range: 3-300PSI/14BAR/14Kgf/cm^2 Measurement Accuracy: (3-100PSI) ±1PSI, over 100PSI ±2PSI Working Temperature: -20 to 60℃ Key Functions: Power button (left), unit switch key (right)Battery: 2pcs AAA1.5V batteries (delivered without batteries) Working Current: ≤3MA or less (with backlight); ≤1MA or less (without backlight) Quiescent Current: ≤5UA Application: Motorcycles, cars, small and medium-sized passenger cars, small and medium-sized trucks.
