For parallel testing on multiple channels

The further development of the MMS is the solution for complex leak and functional testing.

The modular structure and the ZEDsatellite extension enable parallel testing on up to eight measuring circuits.

ZEDmod offers the highest technical standards and completely new software.


Measuring methods


RD relative pressure (optional: 2-channel)


relative pressure with bell testing


relative pressure with flow rate


differential pressure


mass flow

Technical data: Relative pressure Differential pressure Mass flow Flow rate
Test pressure range Vacuum – 16 bar Vacuum – 8 bar
Test pressure accuracy 1% of the end value
Measuring range As with test pressure range -100 – 100 mbar 0 – 50 ml/min up to 200 l/min
Measurement resolution 0.5 ppm of the end value < 0.02% of the end value
Smallest measurable pressure change (type-specific) 0.5 Pa (1 bar) – 4 Pa (16 bar) 0.1 Pa
Measuring accuracy (leak rate) Depending on the test setup Depending on the test setup Typically 3% 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)
