1. GENERAL INFORMATION
Thank you for purchasing Hydrogen (H2) Leakage
Detector. Read though the instruction manual before
operation for correct and safe usage. Please store
and retain this instruction manual for future reference.
1.1 SAFETY USE AND WORKING
ENVIRONMENT
Hydrogen (H2) Leakage Detector only is used by
persons who have necessary knowledge, skill and
know-how for Hydrogen Leakage.
It is designed to detect the leakage for a mixture
consisting of 95% nitrogen and 5% hydrogen.
Please keep the working environment in the moving
fresh air. Don’t work the detector in the confined space
or in closed room.
1.2 HYDROGEN
INFORMATION
Hydrogen is the lightest element. Therefore, it
spreads and volatilizes very quickly. At standard
temperature and pressure, hydrogen is a colorless,
odorless, tasteless, non-toxic, nonmetallic.
But over 5% Hydrogen is highly combustible and
explosive. The lower explosion limit for 100%
Hydrogen is < 4% and for Forming Gas (a mixture of
hydrogen and nitrogen) is 5.6% at room temperature.
A mixture consisting of 95% nitrogen and 5%
hydrogen is not inflammable (see ISO 10156), non
