10.4.5 Chemical resistance
Parts in contact with medium are chemically resistent against:
• Dissolved acids and bases
• Hot water and steam
max. 135
˚
C (275
˚
F)
• CO
2
up to 100 %, with trace sensor COS22-*3 only
NOTICE
Hydrogen sulfide and ammonia reduce the durability of the sensor
►
Do not use the sensor in applications, where the sensor is exposed to hydrogen sulfide and ammonia
vapors.
10.4.6 Cross-sensitivity
Molecular hydrogen causes at least lesser findings and can cause total sensor failure.
