Abstract: A system and method for portable instrumentation is proposed, comprising a server computer and a portable instrument that is wirelessly connectable to the server computer. The portable instrument comprises sensors for performing respective physical or electrochemical measurements, and a hand-held computer that is operably connectable to the sensors. The hand-held computer is configured to record and transmit the measurements to the server computer. The hand-held computer evaluates a real-time wireless connection quality between the portable instrument and the server computer. When the wireless connection quality shows a declining trend, the hand-held computer determines a spatial boundary where the portable instrument reaches a dead zone with wireless connection quality below a predetermined threshold. The hand-held computer then requests pre-recorded data from the server computer to be forwarded to the portable instrument before the portable instrument reaches the spatial boundary.
