Any notable differences, one better than other?
Also are all TC's equal?
Using for forge HT'ing.
I'm not an electrical/electronics type, so what I've read (and I've read a lot lately), means little to me.
HELP!
 
TC have a letter code that tells temperature range. for most knife work, you need a K which is good to 2300F. for forge work, one like this that has ceramic insulation for most of its length should give best life https://www.mcmaster.com/#thermocouples/=1e2o875 at this point, I think you need a digital display for your thermocouple not a PID. you can find displays on amazon or ebay for less than $25 will should do the trick

Thanks Scott, I was thinking PID so I could upgrade to that later but just use it and the TC as a pyrometer right now.
 
Either one will work. The one with the SSR and heat sink will give you the parts you may want later.

You need a type K, 8 gauge (3.2mm) TC and a ceramic sheath.
 
Honestly, I’d say one Chinese/import PID is probably as good as another these days. The main difference I see among them is how they integrate into your relay control. Some need an external power source to drive an SSR, for instance.

I just bought a “mypin ta4” pid to replace a much more expensive version that I had bought from Auberins.com (not complaining, it lasted 10 years). It basically works exactly the same as far as I can tell, though I did need to wire in a power supply for my ssr, as this PID doesn’t supply voltage like the more expensive version it replaced. Just something to keep in mind.

Other than that, PIDs are pretty basic.
