Tel-Tru BQ300 Barbecue Grill Thermometer Review

Tel-Tru BQ300 Barbecue Grill Thermometer Review

The Tel-Tru BQ300 Barbecue Grill Thermometer is an accurate and easy-to-read instrument intended to replace the small, inaccurate units found on many grills/smokers. With its rounded probe, it is not intended to be inserted into food, although you could probably force it. It has a wide temperature range, but lacks a Celsius scale. The back of the thermometer has a 1/2″ NPT thread that will fit through a 7/8″ hole. An accessory nut can be purchased at additional cost. Different probe lengths are available, as well as some that do not glow in the dark – this one does! The thermometer can be calibrated by turning a large nut on the rear, although it came well adjusted from the factory.

We took some additional readings to cover the range that this unit has. The results are:
100ºF actual reads ~101º
200ºF actual reads 203º
500ºF actual reads 492º

The manufacturer’s contact info is found on the packaging, including address, telephone number, e-mail and website. There is no explicitly stated warranty.

This is a heavy duty, large dial thermometer that reads accurately and should fit its intended purpose well. At nearly $57, it is pricey but well made. We’ll give it a Gold medal for exceeding expectations.

Our Favorite Backyard Smoker

The amazing Karubecue is the most innovative smoker in the world. The quality of meat from this machine is astonishing. At its crux is a patented firebox that burns logs above the cooking chamber and sucks heat and extremely clean blue smoke into the thermostat controlled oven. It is our favorite smoker, period.
