4 Precautions
Read this user manual carefully before using the instrument. Hydrogen Leak
Detector Sensistor ISH2000 is extremely selective. Only Hydrogen Sulphide
(extremely toxic) gives a comparable response to hydrogen.
4.1 When working with gas
The normal risks associated with working with all compressed gases must be
considered.
Before connecting tracer gas: confirm that the connectors or test object is designed
for working at the test pressure.
Note: INFICON AB can not take any responsibility for the consequences arising from the
inappropriate use of certain test pressures.
WARNING!
Pure hydrogen is a flammable gas. Only use
ready-made Hydrogen Tracer Gas of 5%
Hydrogen in Nitrogen. This is a standard
industrial gas mixture used in various industrial
applications.
Note: Whenever the word Hydrogen is used in this
manual it implies that the hydrogen gas is safely
mixed with Nitrogen in the proportions 5% H

-
95% N

.
WARNING!
Since the tracer gas mix contains no oxygen,
releasing large amounts of gas in a confined
space may lead to asphyxiation.
WARNING!
Compressed gases contain a great deal of stored
energy. Always carefully secure gas bottles
before connecting pressure regulator. Never
transport gas bottle with the pressure regulator
fitted.
WARNING!
Pressurising objects at too high pressures can
result in a burst object. This in turn can result in
serious injury or even death.
Never pressurise objects that have not
previously been burst tested or otherwise
approved for the chosen test pressure.
