Abstract: This paper discusses the selection and development of a micro-computer-based data acquisition system used for collecting aquifer test data. Primary components of the data collection system are a Colby PC transportable personal computer equipped with an analog-to-digital converter board. The computer is capable of accepting a 12 VDC power input. Data acquisition is controlled by a Basic program and data are stored on floppy disk. At present, ground-water levels and well discharge are measured using pressure transducers. All components, except the transducers, are housed in a cabinet in a field vehicle to minimize environmental effects.
