This product is neutral and non-standard, suitable for mall sale, all new, exquisite workmanship * * * *

mechanical tire pressure has a long life, no serious beating, and can be used for ten years. However, the disadvantage is that the error is much larger than that of the electron, so you need to remember the error * * * *

in addition, the classification of Alibaba tire pressure gauge cannot be combined, but the picture is three in one. Please distinguish which type according to the main picture. Do not shoot wrong ~

[Product description]]
uniquely designed tire pressure gauge, easy to use, easy to carry, O-type returnning spring button design, press it and return to zero directly, very convenient and practical.

"Product Features]
1. O-type returnning spring key design, metal texture mechanical tire pressure gauge, easy to use, good durability and accurate reading, used to read air pressure of cars, motorcycles, bicycles, etc, make sure that the tire can be used under the correct pressure.

[Note]]
1. Please measure the tire pressure in the cooling state of the tire.
2. Press the tail end of the tire pressure gauge tightly on the door mouth of the tire pressure gauge, knowing that the tire pressure gauge pointer moves to the highest position.
3. Please keep the front vertical direction with the tire pressure gauge and read the tire pressure.
4. Please check the tire pressure value (the pressure value is often engraved on the side of the tire) and keep the tire pressure correct.
5. To prevent elastic fatigue of internal parts of the pressure gauge, press the pressure relief valve to eliminate the pressure inside the pressure gauge.
6. After measurement, lock the lid on the tire valve again.
Pressure unit conversion table: 1BAR = 14.223PSI = 100KPA = 1.019/CM2

tire pressure gauge is a tool for measuring vehicle tire pressure. Air pressure is the life Gate of tire, too high and too low will shorten its service life. If the air pressure is too low, the deformation of the body will increase, and cracks will easily appear on the sidewall. At the same time, flexing movement will occur, resulting in excessive heat generation, promoting rubber aging, cord ply fatigue and cord breaking. If the air pressure is too low, it will increase the ground area of the tire and accelerate the wear of the tire shoulder. If the air pressure is too high, the tire cord will be excessively stretched and deformed, and the elasticity of the tire body will decrease, which will increase the load on the car during driving. In case of impact, internal crack and blasting will occur, at the same time, too high air pressure will accelerate crown wear and reduce rolling resistance. Tire pressure gauge can accurately measure the tire pressure, so as to monitor the tire pressure at all times and ensure your driving safely. It is best to measure it before running at high speed. Many names of tire pressure gauge are mainly: tire pressure gauge, digital tire pressure gauge, tire pressure gauge, vehicle Digital Display tire pressure gauge, professional tire pressure gauge of automobile, digital tire pressure gauge, automobile electronic tire pressure gauge, electronic tire pressure gauge.......... And so on.
