The fatigue test bench for low-pressure gauges uses gas (such as air or nitrogen) as the test medium; it is primarily designed to conduct low-pressure cyclic, fatigue, and durability tests on various low-pressure instruments and their components, in order to evaluate their durability and fatigue life.
The HGP series utilizes electro-hydraulic servo control, offering precise pressure regulation, a wide pressure testing range, and high operating frequencies.
The PGP series is gas-driven and meets essential fatigue testing requirements, featuring stable performance, simple operation, and ease of maintenance.
