Features: With quick connection, deflation function, air pressure measurement, etc. At the same time, it adopts LCD liquid crystal display, which has high precision and long service life. Material: Aluminum alloy copper rubber Display mode: LCD digital display Pressure unit: Four units can be switched: PSI, KPa, Bar, Kgf/cm^2 Measuring range: 3~230PSI Measuring accuracy: (3-100PSI)±1PSI, above 100PSI±2PSI; Working temperature: -10 to 50°C Key function: Switch key (left), unit switch key (right) Working voltage: DC 3.1V (with a pair of 1.5V No. 7 batteries) can be replaced; when the battery voltage is lower than 2.5V, the LCD battery symbol flashes Operating current: ≤3MA or less (with backlight); ≤1MA or less (without backlight) Quiescent current: ≤5UA Hose length: 36cm / 14.0in Batteries: 2 x AAA batteries (not included) Application: Suitable for most cars, trucks, motorcycles, and bicycles. Cast aluminum alloy body with valve Brass clamp with clip Built-in pressure relief device to reduce pressure Measures tire pressure from 0 to 230 psi Displays KGF, BAR, PSI, KPA measurements LCD display with backlight for easy reading Pistol-grip control handle Cast aluminum handle with valve Portable size, perfect for putting in the car, easy to Use Suitable for most cars, trucks, motorcycles, and bicycles How to use: 1. Unscrew the tire valve cap. 2. Attach the gauge's copper head to the valve. 3. The device will display the pressure. 4. You need to find an air pump and an air tube to connect the air nozzle, hold the handle of the product to inflate it through the inflator, and vice versa when the pressure is low. 5. After the measurement is completed, unscrew the copper head and press to release the air, so that the indicator is at 0. Delivered quantity: 1 piece becomeveryrich
