O-probes are not just for reduction firings, they are even more useful to d=

firings, not
to measure reduction, but to save fuel. Because the salt kiln may have some=

soda in the environment the sensor end is coated with ITC 213--specifically=

designed to
protect heated metal.
While I said the probe can be used in wood firings, I don't use it for that=

as I agree it
wouldn't provide much useful information.
Interestingly, on the advice of Feriz Delcic I have coated the outside of t=

I have developed a cheap version of the probe which uses the standard oxyge=

and costs about $485. The probe has seen much use in the college kiln room-=

I would not dip my oxiprobe into ITC. I contacted a supplier of O-probes=

they said that "Applying ITC 213 will void the 90 day warranty since it w=

Also on kilns, this manufacturer doesn't recommend applying ITC and it vo=

But do what you want.
Not sure why the auto industry doesn't take your suggestion of ITC on exh=

systems if it saves 10% on fuel? (This means that the US could save 1 mi=

John,
The Bacarach CO2 analyzer might be a solution for folks that
need an analyzer to fire a vapor kiln. It draws in atmosphere into a
tube and cools it in a copper coil before it goes into a fluid.
Fired the soda kiln at NCC last night, 97*F and 117 heat index.
Hottest part was pumping soda solution. I'd take breaks outside to
cool off between applications with the garden sprayer.
