If you look on the side or bottom of the bag you'll see the url for agri recycle. Note you can't see it in the posted pics.
Well, I couldn't wait for a full test(AKA, I didn't feel like cleaning the stove there was a race on!) So I throw a couple a bags in after I ran the hopper out of the stove chows. Preliminary Observations: A bit dusty and a fair amount of fines stuck to the bags after I dumped them. Heat was real nice for a hardwood blend. I got 258*F which killed tha chow and the MWP I am currently burning. Ash looks around average-ish from what I could tell from an already dirty stove. A bag is saved in the test pile for another day. I'd buy these again at the current price unless I see AWF or one of the other box store stand outs. Heat alone made me sit up a little!

Jay I had a ton of them from tracotr supply a year or 2 back, and I absolutely loved them. No clinkers, the ash was moderate and very good heat for the price. If I could find them here, I would buy 2 ton and resupply!
I use a fancy digital meter that uses a thermocouple. I have the thermocouple measuring the convection air and not stove temp. You can use any thermometer, Some also use the wood stove stick on guages. As long as you measure from the same place and keep things like stove heat setting the same. You'll get a decent comparison. Some of the gang bought grille type meat thermometers and stick down in the convection tubes. slvrblkk Just bought a thermometer IIRC. He might also have some tips for ya.
That's a great question that unfortunately I can't answer but like Jay said same place and same heat settings. If you have an IR gun you can go around all parts of the door and such and see where you get a good reading from.
Drill a tiny hole at the base of the outlet duct(close to the stove/furnace) just big enough for the probe to fit in. Stick the probe in the hole. Mark the thermocouple wire so you stick it in the same depth every time. Should work like a charm.
