ル高度計。A barometric pressure detector using a semiconducting semiconductor that extracts the value of atmospheric pressure as an electrical signal, and an A/D converter that converts the electrical signal from the barometric pressure sensor into a digital electrical signal.
Barometric pressure-altitude conversion means for converting the electrical signal from the A/D converter into a digital electrical signal representing altitude;
'An altitude adjustment switch that is manually operated to transmit an electrical signal representing the reference atmospheric pressure to the atmospheric pressure-altitude converting means, and a digital electric signal representing the altitude of the atmospheric pressure-altitude converting means to display the altitude. What is claimed is: 1. A portable digital altimeter characterized in that the entirety thereof is integrally constructed, and is provided with a display means.
