Page 3: Prologue
Beamex ePG is a portable, hand-held, battery-powered device that is used to generate reference pressure in pressure calibration applications. With ePG you can generate pressure between -0.85 to 20 bar / -12.4 to 300 psi. Since the device does not have a display to indicate the generated pressure reading, it must be connected to an external pressure device with an appropriate display, e.g. - Page 4 (see chapter Service and transportation instructions). Include a detailed description of the reason for the return. ePG is available in two different configurations with different delivery contents: ePG Pump Only (9021000) • ePG with a hand strap • Battery pack (8006030) •...
