PROBLEM TO BE SOLVED: To provide an air micrometer capable of digitally displaying the measured results. SOLUTION: A sensor value from a pressure sensor 21 is converted into a digitized sensor value and output by an analogue digital convertor 31; and a digital treatment part 32 forms a digital display digital value, based on the digitalized sensor value and outputs to a liquid crystal display part 41 and adjusts the digitized sensor value by an adjusting data and outputs to a digital analogue convertor 51 as an analogue display digital value. The liquid crystal display part 41 makes the digital display digital value into a numerical value and displays on a liquid crystal panel 65, and the digital/analog convertor 51 converts the analogue display digital value into a display value is converted into analog and outputs to a meter 71, to display on as an indication needle 81. The digital treatment part 32 corrects adjustment data so as to correlate between the digital display by the liquid crystal display part 41 and the analogue display by the meter 71.
