Zusammenfassung:	PURPOSE:To measure the absolute pressure of gas to be measured, to convert the pressure into the gage pressure approximately by arithmetic operation and to display the gage pressure. CONSTITUTION:In a tightly closed case 1, a gas-pressure sensing part 4, which measures introduced gas to be measured or the absolute pressure of atmospheric pressure, a memory 10, which stores the measured value A of the absolute pressure of the atmospheric pressure, arithmetic processing unit 6, which operates G-A based on the measured gas pressure value G of the absolute pressure of the gas to be measured and converts the value into the approximate gage pressure, and a display part 7 are provided. The gage pressure is approximated and displayed by measuring the absolute pressure of the gas to be measured.
