Smoke X uses commercial-grade Pro-Series probes, designed by ThermoWorks with state-of-the-art materials, built to outlast and outperform all cheaply made houseware probes. With a large, dashboard-like display, track all four channels simultaneously with high/low alarms, max/min, and adjustable volume levels. Smoke X has magnets on the back for mounting or use the convenient flip-out stand. Use Smoke X up to 330-hours on a pair of AA batteries, or plug into AC power (adapter sold separately) via USB-C for uninterrupted use. Smoke X includes control circuitry for Billows BBQ Temperature Control Fan (sold separately) so you can control your smoker temperatures over an entire cook. 9 out of 10 BBQ teams use ThermoWorks devices for winning BBQ. Use what the pros use to get award-winning results. Up your game with Smoke X from ThermoWorks, the #1 trusted name in BBQ.
Smoke X is designed to track temperatures over an extended period of time with moderate-heat cooking methods such as smoking, oven-roasting, deep-frying, homebrewing, and Sous Vide and can be used while grilling. Smoke X is not meant to be used in place of a digital instant-read thermometer, such as a Thermapen ONE or a ThermoPop, or used with broiling.
Two or Four Channels
Smoke X comes in two models: Smoke X2® and Smoke X4®. Both models include one Pro-Series High Temp Air Probe for monitoring your pit temperature.
- Smoke X4 has four channels and comes with three Pro-Series High Temp Cooking Probes.
- Smoke X2 has two channels and comes with one Pro-Series High Temp Cooking Probe.
Pro-Series Probes
Smoke X works with all of our Pro-Series probes. ThermoWorks' Pro-Series Probes are the best in the business for accuracy, durability, and heat resistance. Get the confidence that comes with ThermoWorks probes and meters.
Easily Identify Each Probe
Smoke X comes with 18 High Temp Silicone Color Bands (2 ea. of 9 colors) that roll onto each end of each probe, so you can see at a glance which input matches with which probe.
Water Resistant
Molded-in seals for splash-proof protection rated to IP66, safe for outdoor use. NO additional waterproof bags or cases needed.

*Transmission distance specifications are a complicated thing. Actual real-life experience with transmitted temperature readings depends on many factors. Normally, the specified “line of sight” transmission range is the “best case” range assuming no physical barriers between the transmitter and the receiver and no interference from other radio signals. It would be impossible to print a specification that covered “normal” home-user conditions because of the infinitely variable circumstances under which a transmitting thermometer might be used. Differences in home construction and wall composition is a good example. Concrete, masonry, aluminum siding, metal studs, and metal lathe underneath stucco or masonry are all good inhibitors of radio signals. Interference from other radio signals is also variable (microwaves, cell phones, radio communications, networks, etc.) So the only reliable way to compare device specifications is to give a specification for maximum transmission distance under ideal conditions. If you want to evaluate whether a manufacturer actually meets their literal “line of sight” distance claims you should test the device in a rural area with no physical barriers between the transmitter and receiver and little or no interference from other radio signals.
Another option in comparing devices is to look at transmission frequency. 915MHz is normally better than 2.4GHz at penetrating walls and physical barriers.
If you trust the manufacturer, you can normally rely upon a comparison of “line of sight” specs and the transmission frequency for making a relative comparison of products. If the maker has a sterling reputation for specmanship and build-quality, you should be able to rely on their claims for transmission distance as a means of determining which product will have the best range for you, even if in actual use you don’t get the maximum range in their specification. Remember that the more walls and the greater the radio interference the greater the negative impact on your actual transmission distance. Comparing devices in your actual location is the best way to be assured the signal will work for your conditions.
