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.
