The Flo-tech PFM6 is a series of digital portable hydraulic testers designed for fast diagnostic troubleshooting of all types of mobile or stationary hydraulic systems and components . These self-contained testers provide laboratory accuracy and measure flow, pressure, and temperature simultaneously from a single test point .

Operation is simple, featuring a toggle switch to display either flow or temperature on a large 3-1/2 digit LCD, and a loading valve with fingertip pressure control. The dual-scale helical tube pressure gauge offers pulsation dampening and high overpressure capacity . A platinum resistance temperature sensor ensures accurate readings, and the turbine flow sensor provides fast response . All testers include pressure surge protection for safe operation .

The PFM6 series is available with SAE ports (measuring in GPM and °F) or BSPP ports (measuring in LPM and °C). They offer five flow ranges and can handle pressures up to 6000 psi (414 bar) and temperatures up to 300°F (150°C). Flow accuracy is ±1% of full scale with ±0.2% repeatability .
