Fire Protection Sprinkler Gauges
Fire protection sprinkler gauges are Underwriters Laboratory listed and Factory Mutual approved for fire protection sprinkler service.
The 0-300 psi pressure range is used on “wet” fire sprinkler systems where water is available to the sprinkler heads. The 0-80 retard to 250 psi pressure range is used on dry fire sprinkler systems where the lines are filled with air pressure until system activation. The 0-600 psi gauge is available for systems requiring higher pressures.
