ド用圧力計。[Claims for Utility Model Registration] (1) A manometer is constructed by connecting the lower ends of first and second straight pipes, which are made of a transparent material and are placed opposite each other on the left and right sides, with a connecting pipe, A part of the first straight pipe is provided with an overflow port whose vertical position can be freely adjusted, and the overflow pipe is extended downward from the overflow port, and the lower end of this overflow pipe is connected to a closed reservoir container. A pressure gauge for holding minimum values, with a connecting tube attached to the top end of the tube to connect to the piping to be measured. (2) The pressure gauge for holding minimum values as set forth in claim 1, wherein the upper part of the overflow port in the first straight pipe and the reservoir container are communicated by a gas vent pipe.
