Hydrazine (N2H4)




The zero and span drift specifications assume that the analyzer is equilibrated, and is at constant temperature, with a properly maintained sensor.

Special Note

Certain specification items on this model reflect performance different from most other Interscan analyzers, but are in accordance with NASA guidelines, and the extreme difficulties encountered in low-level hydrazine measurement.
