Gauge type
- Analogue - basic instruments for measuring tyre pressure, which are often more accurate than digital alternatives.
- Digital - backlit display ensures easy readability even under poor lighting conditions.
- Continuous measurement system - consists of four sensor caps that replace regular valve covers. By plugging the base unit into the car's cigarette lighter, you have constant control of the pressure of all four tyres.
Pressure range
The correct pressure for front and rear tyres can be found on a sticker, usually placed on the passenger door frame or on the inside lid of the tank, or in the vehicle's user manual. The pressure should be checked every 14 days, for example when refueling at a petrol station.
- Cars - in most cars, the optimum tyre pressure is around 2.3 bar / atm (230 kPa), so you will only need a meter with a range up to about 3 bars / atm (300 kPa).
- Trucks - in the case of trucks, the tyre pressure depends on the load on a particular axle and corresponds to approximately one tonne per bar (for example, 8 t = 8 bars). So the meter should have a larger range to match the expected load.
Additional features
- Hose - makes it easier to measure the pressure of tyres that are less easy to access.
- Tread meter - can also check the depth of tyre treads.
