ZEDbase+

Good leak testing starts with the basics

The ZEDbase⁺is an upgrade of the ZEDbase with a new selection of intelligent standard additional functions. This enables you to easily adapt the leak testing system to your individual testing requirements.

The device can be set up and operated easily thanks to the intuitive user interface with many standard functions.

Measuring methods

RD	RD relative pressure (optional: 2-channel)
RD / GP	relative pressure with bell testing
RD / DF	relative pressure with flow rate
DD	differential pressure
SD	accumulation pressure
MF	mass flow

(See technical data for available pressure ranges)

Accessories (optional)

Test leak
Leak calibrator
Barcode scanner
External ventilation valve
Temperature compensation
Keyboard
