GALAFIRE 2 3/8 Inch Accurate BBQ Temperature Gauge for Charcoal Grill Pit, Smoker Thermometer and Heat Indicator for Meat Cooking

Fit on my masterbuilt 850 gravity smoker.

Easy installation and accurate temperatures

A bit larger than the one being replaced but looks great and IS accurate.

Perfectly replaces the MB Gravity 560 hood thermometer. Stem is a little longer but it does not contact the middle shelf. Matches the temp reading from my Thermoworks air probe placed on the front of the grate right next to it. Does take a little bit longer for the temp to settle in, and the needle can jump a bit as the temp changes. I know it's not perfectly accurate, but the color ranges and needle can easily be seen from a fair distance, making it easy to keep an eye on things from afar.

The needle on this gauge got stuck after a couple months.. sometimes I can get it loose by slapping the face of the dial, but I think I'll need a new one.

So far I've just got the gauge mounted in my BBQ pit and tested it for temperature accuracy so here's my initial observations:1) I validated the temp against a digital thermometer as you can see in one of my pictures. I'm impressed - the two were tracking within a couple degrees of each other at most - pretty impressive.2) The Amazon listing text says that the gauge is "2-3/8" diameter. The picture attached to the posting shows it as "2-6/8" diameter. I measured it myself as you can see in my other picture and it's actually 2-5/8" diameter.3) The simple instruction sheet included says that you can extend the 2-year warranty by 180 days by going to their website "www.galafire.com/warranty" and registering your purchase. When I go to that page I get a "404 - Page not found" error.I bought it for temperature accuracy and for the ease-of-reading and it fits both those criteria. I didn't have the fogging problem but then again, I tested it on a day when it was over 60 degrees outside so it wasn't real cold. Time will tell if it proves to be a winner but so far, I'm pleased.

Dislike having to drill a larger hole to install.It’s always been under cover of a roof and grill cover when cooled off but it still fogs up constantly.

I purchased this thermometer to replace one in my Akorn grill, because the Akorn stock one was very inaccurate. I immediately tested it in boiling water, and it was spot on: 210F at 930' of elevation here, in Indiana. Na calibration necessary!!FYI: The threaded part of the stem is barely, and I mean BARELY, long enough to install in Charbroiled Akorn grill. I was able to catch the thread with the wingnut and make maybe a half a turn before it was snug. I wasn't able to use the Akorn's bezel, as they are not a match.I'll update this review later, should I find out anything that wouldn't earn this thermometer the 5 stars I'm giving it.UPDATE: I used it now with FlamBoss 500 (top notch temp controller for Kamado grills), attaching the FlameBoss temp probe directly to the stem of GalaFire thermometer. Those two read identical values. The GalaFire responds quickly and accurately displays the correct temperature. I couldn't be happier with it.UPDATE #2: a year later and I'm still happy with this. Still working, still accurate.

Muy bueno
