This is Electrochemical sensor for Hydrogen Sulfide.(Electrochemical Hydrogen Sulfide sensor,H2S gas sensor).
many different detection range available.details see below.
Special detection range can be customized.
The Hydrogen Sulfide sensor Modules are available too.
Size: ready stock for all 4 series. 7 series are produced according to orders.
SCIENOC's Hydrogen Sulfide sensor is very stable in normal circumstance for more than 6 months, and can detect H2S with excellent accuracy and fast response speed without reduction of sensitivity.standard warranty is 18 months from dispatch time.extended warranty sensors can be customized.
SCIENOC's Electrochemical Hydrogen Sulfide sensor can be retrofitted easily to existing product designs.
