What to Look for in the Best Infrared Thermometer
- Start with the temperature range. Cooking and household checks need far less span than engine, oven, or industrial work, so pick a model that covers the highest and lowest temperatures you expect to measure.
- Look at the distance-to-spot ratio, often shown as 10:1, 12:1, or 16:1. A higher ratio lets you stand farther back and still read a small, focused area, which is handy for hot or hard-to-reach surfaces.
- Check the listed accuracy and repeatability. A tighter margin, such as 1.5 percent, means you can count on the numbers when you take several readings in a row.
- Choose a quick response time. Anything near half a second keeps you moving when you need to scan several spots, like different parts of a griddle or a row of vents.
- Pay attention to emissivity. A model with adjustable emissivity gives truer results on shiny metal, stone, and other tricky materials, while a fixed setting works fine for simple jobs.
- Think about the laser. A single dot is enough for most home tasks, but dual lasers show the size of the area being measured, which can make aiming easier.
- Look for helpful readout modes, such as max, min, average, and data hold, plus a backlit screen for dim garages and outdoor grills.
- Consider build and battery life. A sturdy body, drop protection, and auto power-off all help the tool last, and a low battery indicator saves you from surprise shutdowns.
- Read the safety note before you buy. Most of these tools measure surface temperature only and are not made for use on people, so match the device to the job.

The temperature range runs from -58°F to 842°F (-50°C to 450°C). A 12:1 distance-to-spot ratio lets the device measure from a distance, and the best results come from holding it about 14 inches (36 cm) from the target. The number on the screen shows the average temperature of the circular area the sensor is aimed at, not a single point.
A maximum temperature display adds extra insight, and the adjustable emissivity setting helps when measuring different surface types. Etekcity states clearly that it is not meant for human use.

My Opinion
I think the Fluke 62 Max is a sensible match for technicians, mechanics, and serious DIY users who need an infrared thermometer that can take a beating. I particularly like the combination of an IP54 rating, a 3 meter drop rating, and a clip-friendly body, since those details matter on busy job sites.
In my view, the min, max, difference, and average readouts turn a simple point-and-read tool into something more useful for spotting changes across a machine or system. The 3 year warranty also adds peace of mind.
Customers do criticize the instructions as hard to follow, so I believe new users should plan to spend a little extra time learning the controls.

Frequently Asked Questions
What is an infrared thermometer used for?
An infrared thermometer measures surface temperature without touching the object. People use it for cooking, grilling, pizza ovens, HVAC vents, car engines, appliance checks, and finding hot or cold spots around the house.
How does an infrared thermometer work?
It detects the heat energy that an object gives off and turns that signal into a temperature reading. You point it at the surface, press the trigger, and the number appears on the screen in about a second.
How accurate is an infrared thermometer?
Most quality models are accurate enough for everyday jobs, often within about 1.5 percent or a couple of degrees. Results depend on the device, your distance from the target, and the type of surface you are measuring.
Can I use an infrared thermometer for cooking?
Yes, it works well for checking the surface heat of pans, griddles, grills, pizza stones, and frying oil. It cannot show the inside temperature of meat or other food, so use a probe thermometer for that.
What does distance-to-spot ratio mean?
This number tells you how large an area the thermometer reads from a given distance. With a 12:1 ratio, a target about 12 inches away is read as a spot about 1 inch wide, so a higher ratio helps you measure small targets from farther back.
What is emissivity, and why does it matter?
Emissivity describes how well a surface gives off heat. Dull, dark, or painted surfaces read easily, while shiny metal can throw off the result, so a model with adjustable emissivity helps you get closer to the true temperature.
Can an infrared thermometer read through glass?
No, glass blocks infrared energy, so the device ends up measuring the glass itself and not the object behind it. The same goes for most clear plastic.
Can I use it to check a fever?
Only if the product is made and labeled for medical use. Many general-purpose models, such as those sold for kitchens and workshops, state clearly that they are not for use on people.
How far should I hold it from the target?
Follow the distance listed in the manual, since it varies by model. As a general rule, staying closer gives a smaller and more precise measuring spot, while standing too far away makes the device average a bigger area.
Is the laser pointer dangerous?
The laser only helps you aim and does not measure heat. Still, never point it at anyone’s eyes, including pets, and keep the tool away from children.
How can I test if my infrared thermometer is working correctly?
Try it on a glass of ice water, which should read close to 32°F, and on a pot of boiling water, which should read near 212°F at sea level. Small differences are normal, but large gaps may mean it needs new batteries or replacement.
What temperature range should I look for?
For cooking and home use, a range from below freezing up to around 750°F is usually plenty. For high-heat jobs such as pizza ovens, forges, or engine work, look for a model that goes well above 1000°F.
