Thermapen ONE at $74, Down From $115
ThermoWorks is discontinuing the Thermapen ONE, and its own product page calls this a closeout price. It's 36 percent off the thermometer that most chefs and barbecue writers treat as the default: one second reads, accurate to half a degree, IP67 waterproof, five year warranty. When the colours sell through, that's the end of it.
Shop the Labor Day Sale →
ThermoWorks is running a Labor Day sale of 20 percent off sitewide, and unusually for a coupon page, the dates are published: it runs 8/30 through 9/8/2026, with no code to enter because the discount is already in the price you see.
The more interesting thing is happening underneath it. The Thermapen ONE, the brand's best known product, is being discontinued and cleared at $74 against $115. That's a separate closeout rather than the sitewide sale, which matters because ThermoWorks explicitly excludes clearance items from the 20 percent. You get one discount or the other, not both.
Everything below is checked against ThermoWorks' own site, including the promotion terms page that lists exactly what the 20 percent doesn't cover.
Active ThermoWorks offers, September 2026
ThermoWorks publishes both the dates and the exclusions for this one, which is rarer than it should be. The 20 percent runs 8/30 through 9/8/2026 and is already applied to the price on the site, so there's nothing to enter at checkout. What it does not cover: the Gravitas Precision Kitchen Scale, the Thermapen NANO Limited Edition, the Woodland Camo Thermapen ONE, TempTest Plus Blue, all books, services and calibrations, and anything already on sale or clearance. That last exclusion is the one to remember, because it means the deepest markdowns on this page sit outside the sitewide offer.
ThermoWorks runs a discount for people currently enrolled in or teaching at a culinary programme. It's an application rather than an instant code, and the brand states that acceptance is at its own discretion, so treat it as something to set up before you need it rather than at checkout. If you cook professionally or you're training to, it's the only standing personal discount ThermoWorks offers.
Most unused products can be exchanged within 30 days of purchase provided they're still in their original packaging. The catch worth knowing is that only products bought directly from ThermoWorks qualify, so a Thermapen picked up from a third party retailer isn't covered. Returns go through their Utah support team by phone, chat or email rather than a self serve portal.
The headline deal and the reason to look now rather than later. ThermoWorks is retiring the Thermapen ONE and its product page says so plainly, calling this a closeout price. One second reads, accuracy to half a degree, IP67 waterproof and a five year warranty on a thermometer at $74. Because it's clearance, the sitewide 20 percent does not stack on top.
The biggest dollar saving on the site at $136.15 off. RFX is the wireless probe system for long cooks where you want the meat monitored without opening the lid. The discount is on the Dove Grey colourway specifically, which is how ThermoWorks usually clears stock: same hardware, less popular finish.
The NODE base unit at $80.50 from $115, saving $34.50. This is the remote monitoring side of the range rather than the cooking side, useful if you want to know your garage fridge or a fermentation chamber is holding temperature while you're not there.
At $41.30 from $59, SIZZLE is the sensible answer if the Thermapen is more thermometer than you need. Instant read, same brand, a third of the price of the flagship even before this discount.
A buffered probe kit at $115.50 against $165, saving $49.50. Buffered probes read the temperature of the product rather than the air around it, which is why this is the version commercial kitchens buy for fridges and cold holding.
The Air Thermapen at $95.20 from $119, saving $23.80. Built for oven, grill and smoker air temperature rather than probing food, so it complements a Thermapen ONE rather than replacing it. This one is in the sitewide sale rather than on clearance.
The Billows fan kit with damper at $71.20 from $89, saving $17.80. It bolts onto a charcoal smoker and holds your temperature automatically, which is the difference between watching a brisket all night and sleeping through it.
How ThermoWorks promo codes work
ThermoWorks doesn't hand out public promo codes, and during a sale it doesn't need to. The discount is applied to the price on the product page, and the brand states outright that no code is necessary. That's why you won't find reader submitted codes on this page: there aren't any worth listing.
What ThermoWorks does instead is publish its terms, which is more useful than a code anyway. The promotion page names the exact dates and the exact exclusions, so you can check before you buy whether the item you want is in the sale or on a separate clearance price.
The single most useful thing to know here: clearance items are excluded from the sitewide sale. If something is already deeply discounted, the 20 percent will not come off on top of it.
How to get the best price on ThermoWorks
- Check whether the item is on clearance or in the sitewide sale, because you get one or the other and clearance is usually the deeper cut.
- Buy the Thermapen ONE now if you want one. It's being discontinued, and a closeout price on a five year warranty product doesn't come back.
- Look at the colourways. ThermoWorks discounts less popular finishes first, so the Dove Grey RFX kit is the same hardware as the full price version.
- If you cook or teach professionally, apply to the culinary programme before you shop rather than at checkout.
- Buy direct. Only products purchased from ThermoWorks are eligible for exchanges.
About ThermoWorks
ThermoWorks is a Utah company that makes measurement instruments for professional kitchens, food safety and industry, and happens to be best known for one product: the Thermapen. It reads in about a second, holds accuracy to half a degree, and has been the standard recommendation in barbecue and baking circles for years.
The wider range runs from the cheaper SIZZLE instant read up through the RFX wireless probes for long cooks, the Billows fan kits that automate a smoker, and the NODE remote monitors used for fridges and cold holding. Warranties are long, typically five years on the flagship thermometers, which is part of why the brand rarely discounts outside set promotions.
ThermoWorks vs other kitchen thermometers
The brands people weigh against a Thermapen. The gap is mostly speed, accuracy and how long the warranty runs.

- The Labor Day sale is confirmed and dated by ThermoWorks itself: 8/30 through 9/8/2026, 20 percent off sitewide.
- The other highlighted months are the grilling season and holiday windows when a thermometer brand would normally promote. ThermoWorks doesn't publish a yearly calendar, so treat those as where to look rather than a promise.
- Closeouts don't follow the calendar at all. When a product is retired, as the Thermapen ONE is now, the discount appears whenever the decision is made and lasts until the stock is gone.
What stacks and what doesn't
1
Sitewide sale plus clearance. It doesn't. ThermoWorks excludes items already on sale or clearance from the 20 percent, so the Thermapen ONE closeout is its own price.
2
Sitewide sale plus books. It doesn't. All books are excluded, though the cookbooks carry their own 30 percent discount.
3
Sitewide sale plus the culinary discount. Assume not, and ask before you order. The culinary programme has its own terms and ThermoWorks approves applications individually.
4
Sitewide sale plus a promo code. There is no public code to add, and any site claiming one during a no code sale is guessing.
ThermoWorks deal questions
Does ThermoWorks have a promo code?
No public one. During a sale the discount is already in the price and ThermoWorks states that no code is necessary, which is why you won't find reader codes listed here.
How long does the Labor Day sale run?
ThermoWorks publishes the dates: 8/30 through 9/8/2026, 20 percent off sitewide. That's unusually specific for a retail promotion and it means you can plan around it.
Why is the Thermapen ONE so cheap right now?
Because it's being discontinued. ThermoWorks calls it a closeout on the product page. It's $74 against $115, and once the colours sell through the model is gone.
Can I stack the 20% with a clearance price?
No. The promotion terms exclude items already on sale or clearance, so you get whichever discount applies to that product, not both.
What else is excluded from the sitewide sale?
The Gravitas Precision Kitchen Scale, the Thermapen NANO Limited Edition, the Woodland Camo Thermapen ONE, TempTest Plus Blue, all books, and services and calibrations.
Can I return a thermometer if I don't get on with it?
Most unused products can be exchanged within 30 days in their original packaging, but only if you bought direct from ThermoWorks. Anything bought through another retailer goes back to that retailer.
The Bottom Line
ThermoWorks is refreshingly straightforward about discounting. The sale has published dates, the exclusions are listed in full, and there's no code to hunt because the price on the page is the price you pay. That makes this an easy month to buy: 20 percent off almost everything until 9/8.
The thing actually worth acting on is the Thermapen ONE at $74. It's a closeout on a discontinued flagship with a five year warranty, it can't be combined with the sitewide sale because clearance never is, and when the stock goes the price goes with it. If you've been meaning to own the thermometer everyone recommends, this is the cheapest that decision is going to get.
