IR gun

[etiger2007]

When I get my stove top magnetic therm up to 750-800 Ill shoot it with the IR Gun, the IR gun tells me the stove is around 650-670. Seems like when I tested both last year at around 600 on the magnet therm the IR gun was closer maybe 650. I want to rely more on my IR gun than the magnetic one to be more accurate, would you? I shoot the laser about three feet back from the stove top with fresh batteries.

I wonder if anybody knows what you could use to calibrate, or otherwise check the IR gun for high temps, like 600 to 700 degrees?

3 feet is too far. Check the manual for the distance-to-spot ratio of your IR gun. E.g. if it says 2:1 you are measuring a spot 1 inch in diameter at 2 inch distance. Depending on that ratio you may measure the whole stovetop instead of the hottest spot. I use mine at about 4 to 5 inches distance in the hottest area I have found so far.

Stove top thermos are notorious for incorrect readings. I would probably tend to believe the IR over the stove top if there is a discrepancy.

You can calibrate with boiling water (212 f) and ice (32 f).

You have to calculate boiling at your elevation. Here it is significantly less than 200 F. I believe it is less than 190, but I'd have to think about it a while.

Any recommendations on IR gun? Seen many with HF? Are they any good? Would like to use for bbq too.

I just bought one about a month ago. It is a Raytek MT6 I bought off Amazon. So far, it works very well. I read through many reviews and asked around on a tool forum and decided on this one based on what I found.

However, I have never had or used one prior to this, and this one is new, so I don't have much experience at this point.

Steve, you're bunch of step ahead of me. At least you have one. I am still in the process of reading all reviews.

Are you planning to get into hvac repair or energy auditing? :-D

 

[MishMouse]

Using something like that could save money when doing it for energy audits.

It would save money in the long run...
Something like that would be nice to have if you had an over fire or a pipe over heat to ensure that nothing was damaged.
And it goes over 1K so that is a plus.

Don't think my wife would buy the above arguments though...

Ed, I too would tend to believe the IR before the magnetic. Try it at different distances and see if you get different results.

I just got a nice Fluke for work. The stove temps are 100 degrees or more different from side to side of the top and other locations. I guess it depends on the internal flow of heat off the burn. My Magnetic is at the top, back right. It reads very close to the same with the IR. The temp at the base of the single wall 5 inches above the stove is the same temp as the magnetic on the top. I can shoot that spot from the couch. IR is a fun toy but not needed.

Truth be told here, I don't, and I don't think you need anything to accurate. In the burn cycle the temps go up and come down, you can see the load, draft ect,. I can guess what the stove top temp is at anytime. Of course I'm not saying it can be of by 200 degrees. I guess this can change if you need to run at the limits of the stove to heat the house. I'm normally 200 - 300 maybe 400F
