applications. Tested to a variety of hydrogen and automotive
standards, the AST2000 series combines the best mechanical design
for hydrogen measurement with high performance digital
compensation.
Benefits
One piece design
All 316L wetted material for optimal compatibility
No oil-filled cavities leave no chance of containment
Non-welded diaphragm eliminates leak paths and weak points
Digitally compensated
Krystal Bond™ Technology
Applications
PEM Fuel Cells l Hydrogen Storage
Hydrogen Filling Stations l Test Stands
Back Up Power
