Typical Analysis of Grade 4.0 Dry Nitrogen
-Nitrogen (N2) Greater than or equal to 99.9%
-Oxygen (O2) Less than or equal to 10 ppm
-Water Content (H2O)* Less than or equal to 10 ppm
-Hm2n Less than Or equal to 10 ppm
*At maximum filling pressure
A pressure regulator designed for nitrogen must be used to reduce the cylinder pressure to a safe working pressure.
