This thermometer has a huge 3 inch black face with three easy to read colored heat zones. This allows you to read your thermometer from quite a distance away. The stem is 4 inches long and .250″ Diam made for use on larger off-set smokers. Tel-Tru is proudly Made in the USA
The stem is threaded at 1/2″ NPT and will fit any 7/8 inch hole and will easily mount using the installation kit if your pit is not already set up for it. Mounting nut and washer are NOT included, sold separately here.
This Tel-Tru BQ300 long stem barbecue thermometer will mount into a 3/8″ hole. If this sounds large to you that is because it is. Most higher end off-set smokers already have this size mounting hole on them and it is just covered with a plug, some are even threaded to accept it. The NPT threading is a standard found in plumbing and for laboratory thermometers.
Tel-Tru BQ300 long stem mounting instructions:
You can see how large that 3 inch dial face is when mounted on an 18 inch kettle grill (shown above). It is about the size of your fist. Another thing to notice in that image is that it does not sit flush, this is by design to get more accurate readings.
Is the Tel-Tru BQ300 Long stem right for your smoker?
For accurate temperature readings, the length of the sensor must be fully immersed inside your cooking chamber. A bimetal thermometer has a coil that is about 2” long located at the bottom of the thermometer stem. A Tel-Tru barbecue thermometer has a 360 degree groove so that you can visualize where the sensor is inside the thermometer stem.
You also need to consider where your food will be on your cooking grates, you do not want the stem right up against it. The longer 4 inch stems are difficult to place at grate level in a small smoker but fit well in the large commercial versions
