The Fox 40 digital manometer is used to easily and quickly measure the air pressure in balls.
With it, you can accurately read the value of the air pressure in the ball, fill it if necessary, or release excess air through the built-in exhaust valve.
It is designed with a quick-release valve that allows air to be released without removing the needle or gauge from the ball.
PSI, BAR, KG and kPa options are available – the default mode is PSI.
The set includes a manometer and three metal needles.
