Ion ReferenceGauge IRG080
The accurate and reproducible standard
in vacuum pressure measurement.

The accurate and reproducible
standard in vacuum pressuremeasurement.
Precise and stable vacuum pressure
measurement is an essential but demanding feature in advanced industrial production processes andmetrology.
Ionization gauges are the only instruments capable to measure totalpressure in the ultra-high vacuum
range. They are versatile and havelittle changed since the 1950s.
Ion Reference Gauge IRG080 and thecorresponding controller IRC081 set a
new standard within the ion gaugespanorama, offering unprecedented
accuracy, repeatability, reproducibility
and long-term stability within a robust
design.

 The IRG080 is the first gauge
complying to the new ISO
standard TS 6737 for ionisation
vacuum gauges.

n Developed in collaboration witha pan-European consortium ofvacuum institutes spanning frommetrology to High Energy Physics.

n Stable electron emission, known
ionization path, lack of influence
from ESD or X-ray effects andpredictable sensitivity for gas
species are among the numerous
innovation features.

n The IRC081 operating and display
interface gives precise andpractical control of the IRG080
gauge parameters - the user has
full control.
