In our stores, prices for pressure gauges start at 250 rubles. 0.15-10.0bar Many sources often equate atm readings (kg/cm2) to kPa/100, but this is not the case. All pressure gauges that I have seen measure pressure either in Bar or Psi, and we are used to measuring in atm or kg / cm2. It was decided to find a device that measures in the units I need. After the measurement, the readings are broadcast for 10 seconds, and then they are reset (disappear from the screen). In reality, the readings differ by a couple of acres. 0.15-10.0kg/cm2 When I connected the pump, I saw that the readings on the pressure gauge in the pump were slightly more than 140 kPa. After 30 seconds, the device switches off automatically. Here are a couple of photos of the included pressure gauge:

I’ve been eyeing off-line pressure gauges for a long time, as my own pressure gauge was seen to underestimate readings. As stated in the description, the pressure gauge provides data in 4 units: Operating mode: the pressure gauge is controlled by one button. On a regular pressure gauge it was 180 – 185 kPa, which corresponds to 1.83-1.88 atm (kg / cm2). Electronic pressure gauge showed 1.94 kg/cm2 For reference: After inflation, the electronic pressure gauge showed 199 kPa, and the regular one 190 kPa (the regular one is taken at an angle in the photo, so it seems that there is 200 kPa). 2 atm = 2 kg/cm2 = 28.446 Psi = 1.96133 Bar = 196 kPa. The selected unit of measure is retained after switching off the instrument. For example, here is a photo with my regular pressure gauge. I measured the pressure in the front wheel: Now the pros and cons. Looks very small, easily lost in my hand :). The pressure gauge turned out to cost 130-140 rubles. 2-150psi
15-1000kPa It turned out 143 on the electronic, against 135 on the staff. This button turns it on, and it also moves the units of measurement. As a bonus, after the measurement, if you press the button, the pressure gauge goes through the units of measurement and automatically recalculates the readings. Measured immediately in kPa, so as not to recalculate. Tests:
This is what came out of it: On the rear wheel, I found that the pressure is small.
