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.

Test pressure accuracy 1% of the end value 1% of the end value 1% of the end value 1% of the end value
Measuring range As with test pressure range - 1.45 – 1.45 psi – 100 – 100 mbar 10,000 – 450,000 ccm/min | ml/min -50 – 50 or -250 – 250 ccm/min | ml/min up to 250,000 ccm/min | ml/min
Measurement resolution 0.5 ppm of the end value
Smallest measurable pressure change (type-specific) 0.5 Pa (14.50 psi / 1 bar) – 4 Pa (232 psi / 16 bar)                 0.1 Pa 0.1 Pa (50 mbar) – 1.5 Pa (6 bar)    
Measuring accuracy (leak rate) Depending on the test setup Depending on the test setup Typically 5% of the measured value, no smaller than 0.5% of the end value
Repeatability Depending on the test setup Depending on the test setup 0.5% of the measured value, no smaller than 0.05% of the end value (depending on the test setup)
