Fieldpiece SOX3 Combustion Check Gas Meter

Not a full combustion analyzer but it does measure O2 and Flue Temperatures. If you are not looking for the full kit and are on a budget, this fits the bill.

Now I won't try to make out like this runs the same kind of features and quality of the 1000 dollar units, but for the price it is from Fieldpiece so you know its a good instrument and it does everything you need an analyzer to do. I would recommend this unit for outfitting your techs that don't need to really detailed analysis but accurately spot-check various smaller issues on heating systems. Still a great buy!
