I've had an Axner Oxyprobe about 20 years. It's always seemed rather finicky and fragile. I've replaced the platinum wire (ouch) a couple times. I've been firing without now for awhile but miss having one. The catalog description of the probe on the ( more pricey)Bailey sounds more sturdy. Wondering if anyone has experience with both.
I'm not sure why one would need a probe in a soda kiln (for example I do noy use my props in my salt kiln)
One can fire by the seat of their pants (my explanation to firing with your eye)
Anyway this is how my probes are mounted in my updraft and car kiln
