Evaluative testing of a prototype barometer

the authors present the evaluative testing of a portable prototype of digital electronic barometer (ubii001). the prototype was developed in venezuela although it includes low-cost multinational parts. the six year evaluation included response stability against atmospheric pressure variations. the ubii00 1 successfully passed a 550-1100 hpa test in the pressurization chamber of the fondo de metrología legal (sencamer, venezuela) and its responses remained within an acceptable ±0.1 hpa stability variation range. the prototype reached an absolute ±0.078 hpa exactitude better than that of ±0.1 hpa required by the world meteorological organization (wmo) and the international civil aviation organization (icao) regulations for surface stations and airports. the information gathered here through the merging of measurement details with prototype characteristics represents a proven and replicable alternative of barometric development.
