HCN-B1 Hydrogen Cyanide Sensor HCN Sensor Description
Alphasense is expanding its line of electrochemical toxic gas sensors to address industry-specific requirements, including emissions monitoring, process safety, environmental monitoring and VOCs.
Hydrogen Cyanide (HCN)
In manufacturing, the use of Styrene Acrylonitrile (SAN) for food packaging and other consumer products has increased the danger of HCN generated during fires. Alphasense has responded to this issue with HCN sensors with fast response and stable output.
Available in A, B and D series.
