Thermometers are frustrating!!!!

Right now I have my two Nu-Temp remote thermometers in the vent. One reads 240 the other 226. I take the 240 one out of the vent and stick it in my brisket and it reads 289. Yeah right?! So I go get my instant read analog Taylor probe and stick it in the brisket - 160. *** Over?! What am I supposed to believe? I know you'll say stick the probe in and if it goes in like it's going in melted butter it's done, but I like to be reassured by a temperature at least. What's a guy to do??? It's a 9lb brisket wholesale cryovac that's been on for about 8 1/2 hours at anywhere from 240-290.
 
I feel your pain. All I have to offer is:

Only trust that which reads 212* in boiling water at sea level, and even then, be suspicious...

Seriously, if you can get a best-two-out-of-three reading with what you have available, go with that. Are you sticking the thermo in the same place each time? -- the point and flat will read differently-- but shouldn't be that different, though. Conventional wisdom suggests that a 9 lb. whole brisket should take about 13.5 hours or more to reach tenderness (which is beyond doneness).

ps: My Polder remote lies just like your Nu-Temp.
 
That boiling water test confuses me. When water starts boiling, it has tiny bubbles. Is that boiling? When it's a rolling full boil, it's boiling. Is that boiling? When do I put the thermometer in? Can't boiling water be various stages of boiling and therefore various temperatures?
 
For the purposes we're looking for here, go ahead and let it come to a full, rolling boil-- for consistency, if nothing else. If I stuck a thermo in even mildly boiling water and it read under 200, or over 220, I would know there's a problem.
 
Ok, both my nu-temp remote expensive probes read around 235 in boiling water. My $12 taylor analog probe reads right around 212. Guess the cheap analog ones are more reliable. So much for having my nu-temps wake me up at night when the temp gets too high or low. I guess I could just always subtract 15-20 degrees.
 
Water can only reach 212 degrees so go for the biggest boiling steaming pot of water you can get. After 212 all you have is steam.
