PFM8 Digital Hydraulic Testers & Dynamometer, 200 GPM, #24 SAE


The all-digital PFM8 Series combines a compact, lightweight hydraulic tester and a dynamometer in one unit. Designed for fast diagnostic troubleshooting of all types of hydraulic systems and components, including engine pump combinations. These testers make all flow, temperature, pressure, and power measurements from one point. A bonus feature of this series is the capability to switch from US to metric units of measure in the field.

Each tester utilizes two digital displays, one for flow and temperature and a second display for pressure and power. Simple operation includes a large format membrane switch for on/off control and selection of units of measure to be displayed. A loading valve with fingertip control and an internal pressure relief system are standard features.

  • Five flow ranges
  • Front panel selectable US or metric readings
  • Dynamometer reads power (HP & kW) directly
  • 3-1/2 digit LCDs for digital display of flow, temperature, pressure, and power
