Abstract
A pointer-type alarm mark structure of a micro-differential pressure gauge includes a transparent casing. The transparent casing has a shaft thereon. At least one alarm index is provided on the shaft. By adjusting the alarm index to a desired position, the user can know whether the pointer of the gauge is within a safe area.
