H2s sensor
H2s sensor
(OP)
Hi folks
I need a H2S sensor that will work in the absence of oxygen.
Our gas is 80% Nitrogen, 20% methane 25 ppm H2S,
Ideally what I want is something with a 1-5V/4-20mA output that covers the range 0-30 ppm.
Everything I've found so far either only works with H2S as a trace in air as they need oxygen or is ridiculously cross sensitive to methane
Any pointers appreciated
Thanks

The sensors used in personal gas monitors (cost c. £/$100) is really what we want, we just need to find one that will work sans oxygen

2) I don't know of a maker, but non-dispersive infrared could be a possibility?
