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.
