SPECTRUM SP Series ENMET Corporation APPENDIX C SPECTRUM SP for Hydrazine SPECTRUM SP For Hydrazine The detection of hydrazine, N2H4, is a specialized application. Generally, hydrazine gas blended in air or nitrogen in known verified amounts is not available to use as calibration gas in the field. Also, the sensor is not responsive to any other gas which could be used as a correlation gas. The sensor itself has a relatively short operating life, and should be replaced every six months.
