PFM6 and PFM6BD Digital Hydraulic Testers


The PFM6 and PFM6BD digital hydraulic test units by Flo-tech are compact, lightweight and completely self-contained. These highly portable testers are laboratory-accurate and are designed for fast, diagnostic troubleshooting of all types of mobile or stationary hydraulic systems and components. All flow, pressure and temperature measurements are made simultaneously from one point.

These units incorporate pressure relief disc protection, low battery/over-range indicators and a helical-type pressure gauge, which provides pulsation dampening and high over-pressure capacity. These units are also available in metric versions.

Unique Features:

  • Large 3-1/2″ digit LCD for flow and temperature.
  • One-way flow.
  • Helical tube pressure gauge.
  • Turbine flow sensor gives fast response.
  • Pressure surge protection with internal pressure relief.
  • Simple operation – one toggle switch controls power, flow and temperature; load valve offers fingertip control of pressure up to 6000 PSI (414 bar).
  • Platinum resistance temperature sensor.
  • SAE ports.
