Abstract: The invention provides a device for testing internal pressure of a hollow sports ball; the device comprising:



(i) a main body (2);
(ii) a removable cap (4); the main body (2) and cap (4) each being provided with mutually engaging formations (12, 14) that enable the main body (2) and cap (4) to be removably secured together by a twisting movement;
(iii) a load cell (46) and associated electronic circuitry for processing an output from the load cell (46); and
(iv) an electronic display (41) linked to the electronic circuitry for displaying an indicator of the internal pressure of the ball;
the main body having an interior void which, together with the removable cap, forms an enclosed ball-receiving chamber for receiving the ball;
the interior void of the main body being provided at an inner end thereof with a seat (44) on which the ball can sit, the load cell (46) being disposed beneath the seat (44); and the associated electronic circuitry optionally being disposed below the pressure sensor;
whereby the ball-receiving chamber is configured such that when the ball is in place in the chamber, the securing together of the main body and cap brings the main body and cap together in an axial direction to compress the ball and apply a pressure through the ball to the load cell, and a force signal sent from the load cell to the associated electronic circuitry is processed to enable the indicator of the internal pressure of the ball to be displayed.
