The PFM6 Digital Portable Hydraulic Tester uses a set of sensors to control the operating parameters of the hydraulic system such as flow rate, pressure and temperature. Pressure can be read directly on the pressure gauge. Temperature and flow rate are displayed on the LCD. The PFM6 Tester is very handy tool for setting, diagnosing problems and controlling the mobile and industry hydraulic systems.

Flow measurement: from 15 through 757 lpm; maximum pressure: up to 414 bar.

The Flo-tech PFM6 Digital Portable Hydraulic Tester is a compact, lightweight portable instrument designed for fast diagnostic troubleshooting of all types of mobile or stationary hydraulic systems and components. These self-contained testers feature laboratory accuracy and provide flow, pressure and temperature measurements simultaneously from one point. Simple operation includes a toggle switch to display either flow or temperature readings and a loading valve that operates with fingertip control.

The dual scale helical tube pressure gauge offers pulsation dampening and high overpressure capacity. For safe operation, all testers include an internal pressure relief system. All testers contain an internal platinum temperature sensor for measuring the temperature of the fluid as it passes through the flow meter body.
