Portable Hydraulic Testers

Installation & Operating Instructions

Introduction

The Omega HFP Series Portable Hydraulic Testers are designed to provide fast diagnostic troubleshooting of hydraulic
systems and components. These compact, self-contained testers feature laboratory accuracy and provide fl ow,
temperature, pressure and optional power measurements simultaneously from one point.

Omega offers two models, each available in a choice of up to 5 fl ow ranges and 3 port sizes:

HFP-110 and HFP-120 Series Digital Hydraulic Tester

Features:

• Accuracy of ±1% of full fl ow range

• 3-1/2 digit LCD display for fl ow and temperature

• Helical tube pressure gauge

• One toggle switch to control power and select fl ow and temperature

• Loading valve with fi ngertip control of pressure up to 6000 PSI (414 Bar)

• Platinum resistive temperature sensor

• Pressure surge protection

HFP-100 Series Digital Hydraulic Tester & Dynamometer

Features:

• Accuracy of ±1% of full fl ow range

• 3-1/2 digit LCD displays

• Digital pressure readings

• Membrane switch to select fl ow, temperature, pressure or power

• Front panel switch to select U.S. or metric readings

• Loading valve with fi ngertip control of pressure up to 6000 PSI (414 Bar)

• Platinum resistive temperature sensor

• Pressure surge protection
