The Fire Extinguisher Pump Action Pressure Gauge Tester is for testing fire extinguisher pressure gauges and demonstrating that they are working correctly. The tester works by applying pressure against the pressure from the contents of the fire extinguisher. This causes the pressure gauge to move if it is working correctly. The gauge will then return to the original position once the pressure gauge is removed.
