A simple push button turns the unit on and selects one of four measurement ranges. With gentle pressure, the nozzle seals onto the valve stem quickly and completely to deliver an accurate measurement. After you’re done, a 30-second automatic shut off means you never have to worry about accidentally running the batteries dead.
When it’s dark, the lighted nozzle illuminates your work area, so you can easily locate the valve stem. The exact measurement instantly displays on a clear, lighted digital screen, so there’s no guesswork or estimation like reading an analog gauge.
Contoured to fit your hand, the ergonomic shape is complemented by a soft, nonslip texture for ultimate comfort and control.
