3HHLM Hydrogen Sulfide Sensor

The 3HHLM CiTiceL is designed for use in applications where methanol might be present. Whilst cross
sensitivity reactions on CiTiceLs are normally readily defined, the behavior of the 3HHLM when exposed to
methanol is significantly more complex, and can not be specified as above for carbon monoxide. The 3HH/LM
CiTiceL is the result of an extensive development project, which has achieved, for this application, a significant
performance advantage over standard 3HH CiTiceLs

CiTiceLs are designed for operation in a wide range of environments and harsh conditions. However, it is important
that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments
and operation.
When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the sensor is
fitted. Do not glue directly on or near the CiTiceL as the solvent may cause crazing of the plastic.
