I found a banks dyna act egt gauge (no Probe). I know everyone says "K" Type but which on? Any of these?

And what do you think about this as an option?

Any K-type should work; they're all the same. Just make sure it's got the right type of physical mounting for your setup.

Gauge wise, I recommend Digital EGT Thermometer Pyrometer w Probe | eBay
It's an Auber 1813. Nice and responsive, accurate; it's got an adjustable high-temp alert light(and relay) so you could setup a buzzer or something if you wanted, and it's bright and easy to read.

 

I see everyone saying that all "K" type are the same but some of the ones I've seen yet I keep seeing different temp ranges listed for them...

 

if you have a banks gauge, get a banks thermocouple and then you will know it will work and be accurate.
