A pressure _____ is a gauge that shows whether a fire extinguisher has sufficient pressure to operate properly.

Explanation:
The pressure indicator is the display on a fire extinguisher that shows whether the pressure is within the safe, operable range. It doesn’t just measure pressure; it communicates a status—usually indicating whether the unit is ready to use. That signaling role is what makes the term indicator the best fit here. A dial or meter is a type of gauge, and while a gauge measures pressure, the indicator specifically conveys whether that pressure is sufficient, which is exactly what the statement is describing.
