It is developed for calibration of internal pressure gauges of pressurized cylinder fire extinguishers used by the numerous manufacturers and repair works. As a result, the pressure in the cylinder will be indicated on the gauge accurately, thereby making the detection of fire extinguisher more visual.
can be used for filling nitrogen to cylinders to be pressurized by nitrogen in the manufacturers of fire fighting equipment. For instance, after the cylinder is filled with dry powder, inactive gas-nitrogen has to be filled for pressurization. When the dry powder cylinder is used for putting out a fire, the dry powder will be sprayed quickly to the flame together with the pressurized nitrogen to extinguish the fire promptly.
