AC400-R00A-CIT Electrochemical Hydrogen Sulfide (H2S) Analogue Gas Sensor For Hydrogen Sulfide Gas Analyzer
Document Purpose
The purpose of this document is to present the performance
specification of the 1series 1H2S hydrogen sulfide gas sensor.
This document should be used in conjunction with the 1H2S
Characterisation Note, the Operating Principles (OP08), and the
Product Safety Datasheet (PSDS 5).
For guidance on sensor performance outside of these limits, please
refer to the 1H2S Characterisation Note.
Output signal can drift below the lower limit over time. For
guidance on the safe use of the sensor, please refer to the
Operating Principles (OP08).
Poisoning
Gas sensors 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 during 1) storage, 2) fitting into
instruments and 3) 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 sensor as the solvent may cause
crazing of the plastic.
