Brad, I did an ebay search for IR analyzer, dispersive analyzer, nothing there. What do I need to search for.
I've seen the heathkits, there's one there now.
What are the principles of a dual thermistor sensor. Something tells me that's what I have too, it would fit the time frame for this unit (early 70's). I noticed there are two rheostats in the sensing box where the exhaust flows to, looks like adjustment controls, in addition to the calibration knob on the main body of the unit. If it is a dual thermistor, how could I check each sensor if necessary?
