 MDG-XB-type fire extinguisher nitrogen filling and calibration of dual-use machine 
 I produced a set of independent R & D will be filled with nitrogen gas pressure gauge of the test combination of two functions as one integrated device, 
 Both can be used to test fire extinguisher nitrogen filling pressure gauge, a machine can realize the optimal combination products, 
 One calibration instrument is available to all fire equipment manufacturers factory or maintenance of a variety of cylinders, fire extinguishers need to install the pressure gauge to check. 
 Pressure inside the cylinder at the pressure gauge on the accuracy of the response to the detection of more intuitive fire extinguishers. Another device from the inflatable school table system and exhaust system composed of two parts, 
 With safe, reliable, easy operation, high efficiency, high precision calibration, is the fire equipment production, 
 Maintenance of fire extinguishers on a variety of manufacturers to gauge the necessary test equipment calibration
