Me?? for the questions? ...if so... the fan is a 6" fan (one of two in housing...a spare too..lol)...plastic blades..all metal motor with "real" bearings in it.... from an expanding wings to fit in a window opening type fan assembly... blow in or out 2 speed big-box store small window fitting fan I had out in the shop for years just sitting.
The PID type thermostat is a "removed from existing controls" industrial control 10 amp continuous capable relay type 'stat that can actually range from -50F to +2500F.... if equipped with the proper range "K-type" thermocouple thingie...depending on which K type thermocouple you pair up with it.. I ordered 2 of the -50F to +200F K type thermocouples from
Ebay...or maybe it was
Amazon?.. several months ago. It's good for +/- one half degree...reads in tenths of a degree...sets like to +100F for one of the REX C-1000 controllers...the other one needs to set at +101F to hit +/- 99.2 to +100.2 air temps-----it's plus 1/2 degree or minus 1/2 degree for air temps from setting with a fast heat/fast decay type heat source (light bulbs or nichrome wire heaters)...egg temps set at exactly 99.7 inside a fake egg with a calibrated solid state thermometer inside.. It's an old solid state industrial controller design from the mid-late90's...they are old industrial takeouts I bought at a fleamarket from the electrician/millwright that took them out of some existing working equipment that was being updated/scrapped. I gave him $5 for 2 of the controllers...bought $12 worth of new K-type thermocouples ($6 cost for 2 plus $6 shipping) and both controller/t-stats work just fine.
I could get inside either one and calibrate them (I found a fix/re-calibrate manual online) to exactly what..but meeehhhh... as long as I know the temps are stable one-half deg one way or another an exact reading on the digital readout is a moot point to me. I tested them in a styrofoam home brew setup for a week each..I like them!
Ebay has the exact ones available...but about the same cost (but shipping is extra) as one of the better solid state t-stats that can keep +/- one tenth degree.. I ran across these at a good "final-closing the doors" price and grabbed both.. I really liked the folks who ran the fleamarket. but it's opened again same place.. different folks..

And dreamchatcher63...if you didn't mean me about the questions...ignore all the above ramblings.
