Product size: 61*32*15MM Accuracy: +/-1 PSI Pressure test range: 3-150 PSI New upgrades (our products are now greatly improved in accuracy, most of the current market is 0.05 bar accuracy, our products are now 0.01 bar accuracy, fully upgraded) First, the accuracy is improved: 1, psi unit mode can be accurate to 0.1psi 2, bar unit mode can be accurate to 0.01bar 3, kpa unit mode can be accurate to 1kpa 4, kg / cm unit mode can be accurate to 0.01kg / cm After the pressure measurement, the reading can be freely converted, which is convenient to use. Specifications: Conversion of the unit of measurement of barometric pressure There are generally four types of air pressure measurement units: psi, bar, kPa, kg/cm2. The conversion relationship between them is: 1 bar =0.069 bar=6.9 kPa=0.07cm2 1 bar=14.5 psi=100 kPa=1.02 kg/ cm2 1 kPa = 0.145 psi = 0.01 bar = 0.01 kg / cm 2 1 kg/ cm2 = 14.2 psi = 0.98 bar = 98.07 kPa Instructions 1. Turn on the machine and press the switch to select the pressure unit you are using. 2. Use the pressure gauge nozzle to press the tire valve to make the contact between the nozzle and the valve tight, and no air leakage can occur. 3. The of the tire pressure is displayed on the LCD screen. 4. Standard tire pressure depends on the pressure standards of automobile manufacturers and tire manufacturers. 5. This product can be automatically shut down, saving electricity and carbon. ,... Package Included: 1* tire pressure gauge Notes: Due to the difference between different monitors, the pictures may not reflect the actual color of the item.
