I used this on my weber 26's; kettle. I inserted it through the top exhaust port and had it dangle just above the food. I don't know if theres a grate clip attachment for this, but if anyone finds out let me know. Keep in mind that this is NOT A MEAT PROBE.
The temperature reading showed that the old dial thermometer that came with my weber was off by 50 degrees! Which explains why it took 12 hours to cook my ribs at what i thought was 225 one time. This thermometer showed that it was actually holding at 170 degrees.
I love this product and have used it multiple times for amazing food. Every one of my cooks has been a great success since i got it. I have been using it with my thermaQ 2 channel setup. Works great for brisket, ribs or any other meat that takes hours to cook.
