Key takeaways
- An infrared thermometer, often called a temp gun, reads the surface temperature of whatever you point it at.
An infrared thermometer, often called a temp gun, reads the surface temperature of whatever you point it at, from a hot pizza stone to a cold fridge shelf to a warm pipe. It is a tool for cooks, hobbyists, and homeowners, not a body thermometer, and the first thing a beginner has to learn is what it can and cannot tell you. It measures surfaces, not the inside of a roast, and shiny metal can fool it.
With a budget of under 100 dollars, you can buy a perfectly capable gun, and the six reviewed here are judged from the facts in their listing titles: temperature range, distance-to-spot ratio, adjustable emissivity, display, and whether a probe is included. Where a title is truncated, confirm details on the listing. Heading into 2026, the key choice is between a general-purpose gun with a wide range for the kitchen and a trade-oriented model from a tool brand for HVAC and household checks. Pick the job first, and the model follows.

How to Choose
Range and the hot end matters
Ranges are quoted in degrees, and many general-purpose guns list about -58 to 1112F, which covers freezers, grills, and pizza ovens. A trade-oriented model may quote a narrower range, such as a few hundred degrees at the hot end, which is plenty for HVAC but not for a hot pizza stone. Before you buy, write down the hottest surface you plan to measure and check that it falls inside the stated range with some margin. Cold-side limits matter as well if you want to check a freezer or a cooler, and a range that starts well below zero is a good sign for that use. Many listings also quote the range in both Fahrenheit and Celsius, so make sure you are comparing like with like.
Distance-to-spot ratio
A ratio such as 12:1 means that at 12 inches from the target, the gun reads an area about one inch across. A higher ratio lets you stand farther away and still measure a small spot. For close-up kitchen use, a lower ratio is fine, but for reading a ceiling vent or a pipe a few feet away, a higher ratio helps. If a title does not state the ratio, confirm it on the listing, since it is the best single measure of how useful the gun will be. A common beginner mistake is to stand too far away, so that the spot grows larger than the object and the gun averages the pan with the stove behind it. Move in close, aim at the center of the target, and take readings from a few spots rather than trusting a single one.
Emissivity and shiny surfaces
Emissivity describes how well a surface radiates heat. Most food, paint, and plastic sit near a default value, but shiny metal reflects heat and can read low. Guns with adjustable emissivity let you compensate, and a common beginner trick is to put a piece of tape or a matte sticker on shiny metal and measure that. If you mostly check pans and pizza stones, adjustability matters more than a fancy display. Many guns ship with a fixed value that suits food and painted surfaces, so for most home uses the default is fine, and you only need the adjustment if you are chasing consistency on bare metal. Reading the manual once is enough to understand which setting to use.
Display, power, and the limits of the tool
A backlit or color display is easier to read in dim rooms, and a hold function lets you lock a reading after you release the trigger. Most guns run on a 9-volt or AAA batteries, so check what is included. Remember that these tools read surfaces only, so they are not suitable for checking the internal temperature of meat or for any body use. For internal food temperature, use a probe thermometer. Also keep the lens clean, because fingerprints and grease can disturb the reading, and wipe it gently with a soft cloth. Let the gun adjust to the room before use if it has been stored somewhere very hot or cold, since a sudden change in ambient temperature can skew the first few readings.
The 6 Best Options
Laser Temperature Gun, Adjustable Emissivity
This generic listing offers a non-contact digital laser temperature gun with a range of -58 to 1112F, adjustable emissivity, and uses across cooking, barbecue, food, and fridge checks. The adjustable emissivity is the most interesting feature for a beginner who wants to learn why readings change on different surfaces, because it gives you a control that most basic guns lack. It is a versatile all-rounder for a household that cooks and also checks a fridge or a vent.
- A wide range covers freezers all the way up to hot pizza stones.
- Adjustable emissivity helps with shiny pans and mixed surfaces.
- Trade-off: it is an unbranded listing, so confirm the distance ratio and battery details.
Skip it if you want a recognizable tool brand, a pocket-size body, or a listing that states its distance-to-spot ratio plainly.
Klein Tools IR5
The IR5 is a trade-oriented infrared thermometer with a dual targeting laser and a 12:1 distance-to-spot ratio, from a brand known for electricians’ tools. It is aimed at HVAC and household diagnostics, such as checking vents, ducts, and pipes from a safe distance. The title is cut off after the low end of the range, so confirm the maximum temperature on the listing before you plan to use it near ovens.
- A 12:1 ratio lets you measure small targets from a comfortable distance.
- The dual laser marks the measurement area more clearly than a single dot.
- Trade-off: the hot end of the range may fall short of pizza-oven temperatures.
Skip it if you plan to measure very hot cooking surfaces, or if you want adjustable emissivity and cannot confirm it on the listing.
Etekcity Laser Temperature Gun
Etekcity highlights a color display with large digits and an easy-to-read LCD, aimed at cooks checking pizza ovens, griddles, and meat surfaces as well as HVAC jobs. The large display is helpful for beginners and for dim kitchens, where a tiny monochrome screen can be hard to read mid-task. It sits in the middle of the list as a friendly, readable general-purpose option.
- A large color display with big digits is easy to read at a glance.
- It is positioned for both kitchen and household uses.
- Trade-off: the title is cut off before the maximum temperature, so confirm it on the listing.
Skip it if you need to confirm adjustable emissivity, a stated distance ratio, or a rugged tool-brand build for jobsite use.
Benetech Laser Temperature Gun
Benetech offers a digital, non-contact surface temperature gun aimed at cooking food, pizza ovens, griddles, meat, and refrigerator checks. It is a straightforward kitchen-focused tool, and the non-contact approach keeps your hands clear of hot steam and splatter. For a first temp gun, a plain model with a clear kitchen purpose can be easier to understand than a feature-heavy one.
- Positioned squarely for the kitchen, the grill, and the fridge.
- A non-contact design keeps your hands clear of heat and splatter.
- Trade-off: the title does not state the distance ratio or the exact range, so confirm both.
Skip it if you need to know the distance ratio before buying, or if you want a pocket-size device with a probe attachment.
Klein Tools IR07
The IR07 is a pocket-size dual infrared and probe thermometer with an LCD. Having both modes in one device is useful if you want surface readings and a contact probe reading from a single tool, and its small size makes it easy to keep in a toolbox, a glove compartment, or a kitchen drawer. It is a different kind of tool from the longer, gun-shaped models.
- It combines infrared and probe functions in one body.
- The pocket size makes it easy to carry and store.
- Trade-off: it is more of a compact tool than a long-range gun, so aiming from a distance is limited.
Skip it if you want a wide kitchen range with a visible laser and a stated distance ratio, or a larger body that is easier to hold steady.
KNINE OUTDOORS Temp Gun
This one lists a range of -58 to 1112F and is aimed at cooking, ovens, BBQ, griddles, meat, HVAC, and engine uses, with the title cut off mid-sentence. It is a general-purpose gun for outdoor cooks and tinkerers, and the range suggests it can handle a grill grate or a pizza stone as well as a cold drink cooler.
- A wide range suits outdoor cooking and household checks.
- Multiple uses are listed, from grilling to engine inspection.
- Trade-off: the title is truncated, so confirm the distance ratio and power details on the listing.
Skip it if you want a tool brand known for trade use, or if you want a clear distance ratio and power source spelled out in the title.
Which One Fits Your Situation
You cook on a pizza stone or griddle
Choose a wide-range gun such as the generic -58 to 1112F listing or the KNINE. Check the stone or pan from a few inches away, and wait a few minutes after the oven reaches temperature so the surface itself has caught up, which is what the gun actually reads.
You work on HVAC or household checks
The Klein Tools IR5 is aimed at that work. Its stated distance ratio makes it suitable for checking registers, ducts, and pipes from several feet away, which is handy when the target is on a ceiling or behind furniture.
You want something pocket-sized
The Klein Tools IR07 combines infrared and a probe. It fits in a drawer or a pocket, so it is easy to grab for a quick check, though it is less suited to aiming at far-away targets than the gun-shaped models.
You want an easy-to-read screen
The Etekcity color display is the standout. If you cook in a dim kitchen or read the screen from an awkward angle, big digits take a lot of squinting out of the process.
Common Mistakes
- Using an infrared gun to check internal meat temperature.
- Pointing it at shiny metal and trusting the number.
- Ignoring the distance ratio.
- Using it as a body thermometer.
- Forgetting to check the hot end of the range.

Frequently Asked Questions
Can I use it on a person?
No. It is a surface tool and not designed for body use. For anything related to health, use a thermometer intended for that purpose and follow its manufacturer’s instructions.
Why does my reading change on shiny pans?
Shiny metal has low emissivity, so it reflects heat from its surroundings. Put a strip of matte tape on the spot, or adjust emissivity if your gun allows it, and measure again.
What does 12:1 mean?
At 12 inches, it measures a one-inch spot.
Do I need a probe too?
For internal food temperatures, yes. An infrared gun tells you how hot the outside is, while a probe tells you what is happening in the middle of a roast or a loaf.
