The Cost of Guesswork in Pressure
Squeezing a ball with your thumbs gives an inaccurate measure of internal PSI or bar pressure. An over-inflated ball puts excessive tensile stress on bonded seams, leading to micro-tears over time.
The Mikasa AG500 Digital Pressure Gauge features a high-precision digital sensor and an integrated micro-bleed valve, enabling match officials to release exact fractions of a PSI with a single press.
- — Basketball official pressure: 7.0 – 9.0 PSI (0.48 – 0.62 bar)
- — Football official pressure: 8.5 – 15.6 PSI (0.6 – 1.1 bar)
- — Netball official pressure: 9.0 – 11.0 PSI (0.62 – 0.76 bar)
