Tel-Tru BQ300 Barbecue Thermometer

The 2.5-inch stem is ideal for thinner-walled grills or setups where space inside the cooking chamber is limited. The 4-inch stem is better suited for thicker-walled custom pits or insulated smokers where you need the sensor to reach further into the center of the airflow.

No, the glow dial does not require any power source. It is designed to absorb ambient light, allowing it to remain visible in low-light conditions during evening or early morning cooks.

Yes, the BQ300 features an adjustable calibration nut on the back of the dial. This allows you to periodically check the accuracy against a known reference point, such as boiling water, and make adjustments as needed.

The BQ300 requires a 7/8-inch mounting hole and uses a 1/2-inch NPT thread. If your grill currently has a smaller hole, you may need to drill it out slightly to accommodate the installation.

The BQ300 is not rated as waterproof. It is built for durability in outdoor environments, but you should avoid submerging the dial in water or leaving it exposed to heavy, direct rain for extended periods.

The RedZone dial provides a visual reference for common barbecue temperature ranges. It helps you quickly identify whether your smoker is in the ideal zone for low-and-slow cooking or if it is running too hot or too cold without needing to interpret exact numbers.
