The rugged PFM Tester Series now features an internal safety pressure relief disc, or “burst disc.” The series has been relied on to measure flow, pressure, temperature and horsepower on mobile hydraulic equipment. Effective immediately, all PFM testers will include an internal burst disc component. The new design ensures that in the event of an over-pressurization, the fluid is allowed to bypass the load valve safely and remain within the hydraulic system.
