Abstract: A testing device and method for inflatable objects comprising an arrangement of transducer sensors; connectors between the transducers and the inflatable object desired to be tested; processors electrically connected to the transducer sensors; a controller electrically connected to and interactive with the processors; and a display of the electrical output. The transducer sensors comprise a pressure transducer, a temperature transducer, and a load cell transducer. The temperature transducer is positioned generally adjacent to the valve nozzle of the inflatable object. The processors of the present invention comprise a multiplexer electrically connected to the transducer sensors, a differential amplifier electrically connected to the multiplexer, and a sample/hold amplifier electronically connected between the analog-to-digital converter and the differential amplifier. The controller comprises an input/output keyboard connected to the processors through an RS-232 communication line.
