The good news is the PID controller I ordered from Hong Kong through
ebay arrived in only 12 days!
The bad news is I was snookered. More accurately, I snookered myself, as
all the info was there had I read it all carefully.
The controller uses a type K thermocouple (−200 °C to +1350 °C / -328 °F
to +2462 °F range), and comes with it.
The control face has 4 digits.
I was surprised to learn it only goes up to 400C. Not quite good enough
for aluminum! I fail to understand why this limitation, as all the
hardware seems fully capable. The limit must be in the micro-controller
programming.
The good news is the thermocouple is killer. Nice braided stainless
steel sheath and crimped on terminal lugs.
Anyone know of an easy mod to make this thing go higher?

You can program the type of thermocouple, so I wonder if I can lie to
it?<GRIN>
