2 inch

Great little gauge that I have put on my Tennessee smoker, works very well and is accurate with measurements in both Celsius and for those left-handed people, Fahrenheit. Very happy with the fitting as well which was super easy and done in minutes.

Does what it says on the tin. Built well, good price for two, easy fit, so far they work well and good. Delivery on time, no damage.

We bought a Weber kettle BBQ without a built-in thermometer built in because it was £80 cheaper than one with! For next to nothing I got these instead which work just as well by simply popping one into the top vent. I didn't even need two but I guess it's good to have two. I cook legs of lamb and whole chickens on our Weber so knowing the temperature is essential. These do the job perfectly. Buy them. :)

Good stuff!

Good value. Have used both straight away. One in a charcoal BBQ to replace original. 1 in a portable gas one. Both seem very accurate. I recommend using heat resistant washers when fitting though.

I bought these to retrofit to 2 of my weber bbq's, they worked perfectly, the reason for 4 stars is the one left outside does fog up when it rains. but that does clear although not sure if the damp in there will have a long term effect on the product

One thermometer has misted after 4 days..

This is a replacement for the gauge on my barbecue which was damaged in the recent wind. The length of the probe had to be identical to avoid the Barbecue's internal folding shelf. Happily the gauge diameter is identical and the gauge display is much clearer than the original. As there were 2 in the box (a single unit was not for sale), I have a spare! Good value for money.
