Relevant cross-sensitivities – DrägerSensor XS EC Hydrazine

The values given in the table are guide values and apply to new sensors. The values stated may vary by ±30%. The sensor may also be sensitive to other gases (data available from Dräger on request). Gas mixtures may be displayed as a combined total. Gases with a negative sensitivity can cancel out a positive hydrazine reading. It should therefore be checked whether gas mixtures are present.

Gas/vapour	Concentration	Reading in ppm N2H4
Ammonia (NH3)	250 ppm	≤ 2.5
Chlorine (Cl2)	10 ppm	≤ 0.1 (−)
Carbon monoxide (CO)	1,000 ppm	no effect
Hydrogen (H2)	1,000 ppm	no effect
Hydrogen sulphide (H2S)	20 ppm	≤ 0.25
Nitrogen dioxide (NO2)	20 ppm	≤ 0.05
