Fire Extinguisher Pressure Alternating Tester

The fire extinguisher pressure alternating test machine meets the test requirements of GB/T4351.1-2005 Portable Fire Extinguisher and GB 8109-2005 Trolley Fire Extinguisher. It simulates filling and applies high and low pressure alternating pressure to the product until the set number of times is reached or failure occurs. It is fully automatically controlled and equipped with an explosion-proof cabin and failure detection device. It has a dedicated pressure alternating control software. The alternating pressure, frequency and number of times are adjustable. During the test, the user only needs to set the parameters and then start the test with one button.
