I  Fire extinguisher pressure test blast detector is researched and designed by our company. This machine is composed of computer, printer, control box and hydraulic test pump ,and it can accomplish the test once and for all . During the test ,it can get the result of yield value , blasting pressure , wading volume , rate of volume deformation , yielding deformation , blasting deformation , length , and it can also draw the graph of pressure-inflow , pressure-time and inflow-time .
