¶ There is not a separate analyzer available for each of these compounds, and the sensor does not respond equally to all hydrazine species. The analyzer must be calibrated with the specific hydrazine compound of interest.
¤ Indicates the analog meter UL classified intrinsically safe version, which must be ordered in most hypergol monitoring applications.
