1. GENERAL INFORMATION
Thank you for purchasing Forming Gas Leak 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
Forming Gas Leak 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 toxic and with on environmental issues. And when it exposes to the ambient air, it quickly
rises.
