What do you think of the tire barometer?

1. The included angle between the center line of the air pressure metering port and the axis of the body is 90-180. The scale is quadrilateral, and the scale value is 0.07Wpa-0.4Wpa Before reading, tap the instrument shell or surface glass with your fingers to eliminate the friction in the transmission mechanism.

2. When observing, the pointer overlaps with the mirror pointer. At this time, the indicated value of the pointer is air pressure, and the reading is accurate to one decimal place. Read the temperature value on the barometer to one decimal place.

Extended data:

It should be noted that there are different standard units of air pressure, generally there are 3~4 kinds. Just like there are three or four marking units such as kg/cm2, bar, PSI and kpa on the barometer, the conversion relationship between them is as follows:1bar =1.02kg/cm2 =102kpa =14.5psi.

Note that if the vehicle needs to be inflated, the pump can be solved on the spot. If there is no owner, you need to go to the nearest tire shop to inflate. It is best to choose the distance to the inflation point not to exceed 1.6Km, because it is accurate that the tire pressure is still within 1.6km after standing for 4 hours. If it exceeds 1.6Km, charge 5% more.

According to relevant data, the standard air pressure of ordinary automobile tires is the best: 2.5kg for front wheels and 2.7kg for rear wheels in winter; In summer, the front wheel is 2.3kg and the rear wheel is 2.5kg, which can not only ensure the safety and comfort of driving, but also minimize fuel consumption.
