ZEDmod

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.

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