Accurate measurement: Align the tire pressure gauge directly with the valve and apply sufficient pressure to form a tight seal. The digital tire pressure gauge provides fast and accurate readings in increments of 0.1. Range of 4 units: 0-150 PSI/0-10 Bar/0-10 Kgf/cm ² or 0-1000 kPa. Suitable for cars, trucks, motorcycles, bicycles, etc. (not compatible with Presta valves). One click control: Simply press the side key "ON/UNIT/OFF" to turn it on, select the desired unit and hold it down for 3 seconds to turn it off. The memory function automatically saves pressure units, reducing trouble. If there is no action taken within 30-40 seconds, the device will automatically shut down to save power (including battery 3 * LR44). Tip: Use the device only at temperatures between -5 ° C and 50 ° C. Nighttime visibility: The backlit LCD screen and light-emitting nozzle provide visibility in low light conditions, while the 10 second continuous reading function makes reading easier and more convenient. Digital displays are more accurate and easier to read than analog instruments, saving time and reducing errors. Compact and portable: The tire pressure gauge is lightweight and compact in structure (13.49 x 5.51 x 2.69 cm); 50g), can be easily stored in glove boxes, door pockets, or center consoles. The hanging ring on the handle makes it easy to carry on the bicycle. ABS material is non slip and ultra light, and the streamlined handle provides ergonomic grip. A tire pressure gauge is an affordable tool that every car owner should have. This is a small investment, regularly checking tire pressure can prevent air leaks, reduce wear, and save fuel.
