Best Magnetic Stove Pipe Thermometer (2026): 4 Compared

Compare the picks

Specifications are manufacturer rated, collected 22 October 2026. None of these listings states a warranty term with a length, and none names a safety standard, so all four score zero for safety and warranty.

How we scored them

Each thermometer is scored on performance, build, value, safety and warranty, using only what the listing publishes. Performance weighs the stated reading range and how readable the dial is; build weighs the stated materials; value weighs what the pack gives for the format, with two-packs earning their keep as spares. The weights are on our How We Pick page.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

Buying guide: the best magnetic stove pipe thermometer

Magnetic surface vs probe

Three of these four are magnetic surface thermometers: the magnet holds the dial against the outside of the pipe, and the bimetal sensor reads the surface temperature. The Imperial KK0166 is the odd one out, a probe thermometer with a magnetic mount whose 4.5 inch stem sits in the flue gas itself, reading up to 1700 F. Surface meters top out at 900 F here. The two types answer different questions, so decide which temperature you want before you shop. Our magnetic vs probe stove thermometer comparison walks through the difference.

Reading range and dial zones

The Sckee, Copkim and Frienda listings state their ranges plainly: 100 to 900 F for the first two, 100 to 800 F for the Frienda. The Sckee dial goes further and paints three zones on the face, COOL, BEST and TOO HOT, so you read the burn at a glance instead of remembering numbers. The Copkim and Frienda listings describe a large dial and a brightly colored needle for reading from across the room. A wide range matters less than a dial you will actually look at.

Two scales on the dial

The Sckee listing states two reading units, Celsius and Fahrenheit, on the same dial. The Copkim listing describes two ways of reading as well, though it names them only as a wide range feature. Before you trust a needle, check which scale your eyes land on; the same mark means very different things in the two units, and the listings do not all label the scales the same way. If you think in Fahrenheit, confirm the dial reads in it before the first burn.

What the dial is made of

Listings name their materials, and the materials decide how the meter ages. The Sckee states a stainless steel pointer and a magnet encased in stainless steel, which the maker says resists high heat and aging. The Copkim and Frienda listings state an aluminum dial, a bimetal sensor, a brass pointer and a metal handle. The Imperial listing states only metal inside and out, which is thin for a probe that lives in flue gas. When a listing is vague about materials, treat the build score as provisional.

One meter or two

Two of these listings sell two-packs. A second meter lets you watch the pipe in two places, or keeps a spare when one meter lives on the shop stove and the other on the house stove. The Sckee and Imperial listings sell a single meter each. If you heat with more than one stove, the two-pack is the practical buy.

Thin listings tell you something too

The Imperial KK0166 listing is three short bullet fragments: a magnetic mount, quick shipping, and a 1700 F register. The spec table fills in the 4.5 inch immersion depth and the metal build, but there is no dial description, no zone marking and no sensor type. A thin listing is not proof of a thin product, but it leaves the scoring with less to work with, and this one lands last for that reason. When you compare, weigh what is stated over what is implied: a stated 4.5 inch stem beats an unstated dial every time.

Around the Woodpile

• Wipe the dial with a soft cloth when soot dulls it; the Sckee care instructions say exactly that.
• A two-pack covers two stoves, or one stove and a spare in the drawer.
• The probe meter reads flue gas through its 4.5 inch stem, not the pipe surface, so do not compare its number with a surface meter’s.
• Check that the magnet holds firm before you trust a reading through a whole burn.

Frequently Asked Questions

How do you use a magnetic stove pipe thermometer?

The magnet holds the meter against the pipe, and the dial reads the surface temperature as the burn changes. The Sckee dial marks COOL, BEST and TOO HOT zones, so you adjust the air by the zone, not by memorizing numbers.

How hot does stove pipe get?

The surface meters here state ranges topping out at 900 F, and the probe states up to 1700 F for flue gas. The Sckee dial’s TOO HOT zone marks where its maker says to back the burn down; treat any single number as that listing’s claim.

Should I buy a magnetic or a probe thermometer?

A magnetic surface meter watches the pipe wall and tops out at 900 F in these listings. A probe watches the flue gas and reads far hotter, to 1700 F on the Imperial. A magnetic surface meter watches the pipe wall; a probe watches the flue gas itself.

Where does the thermometer go on the pipe?

The listings describe a magnet that holds the meter to the pipe, and the probe listing describes a 4.5 inch stem for the flue. Follow the maker’s placement guidance for your stove and pipe, and local code.

Do I need two thermometers?

One meter watches one spot. The Copkim and Frienda two-packs cover a second stove or keep a spare, which is the practical buy for anyone heating with more than one stove.
