We plan to replace the O2 probes on our boiler stacks (Natural gas fired.) We use the signal for excess air control. Can anyone recommend a good O2 in situ stack probe?

 

how much do you want to spend?
go on the web and search for in situ O2 sensors, I found about 10K hits on one site alone.

Get the sample from furnace by extracting take it to cool atmosphere. keep the probe there in a housing and analysis the sample. we have used it in reformer of ammonia plant in Kribhco,Surat.

 

Manufacturers want you to pay a lot for their O2 sensors, It has been my experience with air to fuel ratio controllers, that a simple O2 sensor picked up from the Auto parts store for 5 dollars, works great. Of course you will need to be able to read the signal, usually a DC voltage signal.

 

Are you still looking for o2 probes? We supply O2, CO, NOx, SO2, Co2 etc. pobes, monitos, analyzers, etc.
