BBQ and Smoking Thermometers Monitoring temperature with a leave-in probe BBQ thermometer is the only way to know exactly what’s going on inside a beef brisket, smoked turkey, baby back ribs, or pulled pork butt as they come up to temp “low and slow” in a smoker. Pro barbecue teams wouldn’t dream of going to a competition without one. Dual-channel thermometers with high and low alarms allow you to track your food’s internal temperature as well as the ambient temperature in your smoker or grill. Instant-read digital thermometers are perfect for spot-checking steaks and chops when grilling over high heat.
