Instant-read thermocouple probe
ThermoWorks’ successor to the Thermapen ONE: a folding thermocouple probe for quick spot checks on steaks, roasts and baking.
Instant-read probe (budget)
An affordable instant-read with a backlit, auto-rotating display and a 4-inch stainless probe.
Wireless leave-in probe
A truly wire-free probe that stays in the meat and reports internal and ambient temperature to an app.
Infrared surface thermometer
A popular non-contact temperature gun for griddles, pizza stones, HVAC vents and engines. Surface readings only.
Wi-Fi + Bluetooth room sensor
A small sensor that logs temperature and humidity to the Govee Home app over 2.4 GHz Wi-Fi.
Forehead (temporal artery) thermometer
A home temporal artery thermometer that reads with a gentle forehead swipe. Exergen states it is for use on all ages.
°C = (°F − 32) × 5 ⁄ 9
A thin probe reads the internal temperature in seconds. For long roasts and smoking, add a leave-in or wireless probe so you can monitor without opening the oven or lid.
Read the guidesInfrared thermometers read surface temperature only — they cannot tell you the inside of a steak or a pot of liquid below the surface.
