OK so I have a Rutland stove top thermometer? What are the chances its bad out the package? I borrowed an IR gun from work and my stove top thermometer will read 300 why the IR at the same spot will read 450-500.. New battery in the IR . I don't know which to believe..
 
That's quite a discrepancy. I don't have a lot of faith in Rutland's thermometer. Pop it in a 300F oven for a few minutes and see what it reads.

I've learned to do this too. Seems like my Rutland was, running 50 cool

I learned to do this with new Rutland last year. It seemed to read about 50 degrees cooler than the oven, across the whole range.
 
OK I'll try that. Is it likely to be 150° off?? What the chances the IR is bad its kinda old it from work and from HF. Maybe been dropped a few times.... Guess I'll just have to stick it in the oven
 
LOL, you could try an IR reading off the oven walls once the oven temp has had a chance to stabilize. Of course this is assuming the oven thermostat is in calibration. Often they are off a bit.
 
Lol I mean the thermometer not the IR gun... Thanks for the advice I'll try the oven test when I get home and post my findings
 
Use something to suspend it in a pot of boiling water. That would have to be close? The IR maybe on the side of the pot midpoint of the water level?
 
I don't think my oven goes down to 100 but I'll start it at 2 then go to 3 and such maybe up to 450 and see where its at. Do I need to put it on something or just stick it to the rack? Or wall or where at
 
OK so I put the thermometer in the oven and its spot on. 200-200 300-300 400-400... So now I know the IR is wrong. Thanks for the tip
 
I've got three or four IR's at work and found them not accurate once above 3 or 400 degrees. They all vary widely once above a certain temp.
