Available gases for test leaks
Test leaks are only suitable for specific gases.
► If you want to have a test leak with a gas that is not on
the list please contact us. We will tell you if the test
leak with the gas you request can be build.
► For additional information please see the safety data
sheet of the calibration gas and the quality test
certificate that was added to the test leak.

INFICON Calibrating | 3
Test-leak-sniffer-leak-detection-Operating-instructions-lina80en1-07-(2004) 13 / 18
3 Calibrating
The calibrated test leak constantly emits gas during its
operational readiness.
WARNING
Explosive gas mixtures
Flammable gases can form explosive gas mixtures, see
the gases marked with the flame symbol under
“Technical specifications [}8]“.
► Care for sufficient ventilation and keep away from
ignition source.
► Please also observe the instructions in the safety data
sheet.
üAmbient temperature + 15°C to + 40°C
üIndicated pressure range 0.5 bar to 7.5 bar.
At a pressure of: p < 0.5 bar, the test leak is no longer
operational.
1
Follow the instructions for calibration with an
external test leak as described in the operating
manual of the respective leak detector.
2
Hold the sniffer tip against the exit opening of the
test leak until the measurement result is stable.

4 | Cleaning and maintenance INFICON
14 / 18 Test-leak-sniffer-leak-detection-Operating-instructions-lina80en1-07-(2004)
4 Cleaning and maintenance
4.1 Cleaning the housing
For cleaning the outside of the test leak, a slightly humid
cloth should normally do. Do not use under any
circumstances any aggressive or scouring cleaning
agents.
4.2 Maintenance
Pressure in test leak too low
Test leaks with a pressure < 0.5 bar can no longer be
measured correctly. Proper calibration of the leak
detector is therefore no longer possible.
The calibrated test leak requires no maintenance. When
the calibration gas is used up (pressure < 0.5 bar) the
test leak has to be refilled and calibrated.
Please contact your nearest INFICON Service Center.

4.3 Sending for repair or
maintenance
Do not open defective products.
Contact your nearest INFICON service point.
CAUTION
Calibration gas
Test leaks sent for repair may still contain calibration gas.
► Take account of the national regulations for shipping
the respective calibration gas.
