HCL-B1 Hydrogen Chloride Sensor HCL 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 Chloride (HCl)/Hydrogen Bromide (HBr)
The HCL sensor also detects Hydrogen Bromide (HBr). These HCL sensors are zero biased for easier use.
Available in A and B series.
