Wintact Laser Infrared Thermometer Gun (WT313B) -50°C to 400°C for non-contact surface temperature checks
Product description
The essentials
A laser infrared thermometer gun like the Wintact WT313B is designed for one job: getting a surface heat reading without having to touch the hot object. That makes it handy around cooking and workshop-type tasks where you want a quick answer and you’d rather not hover your hand near flames, griddles or a pizza oven.
In use, you aim at the surface and pull the trigger. The unit continuously scans while you hold it, then it keeps the last displayed reading once you release the trigger. On paper, it targets fast results (0.5 seconds) and a stated measurement error of ±1.5%.
What you’ll notice in everyday use
The idea is simple, but the practical details matter. The backlit LCD helps if you’re checking temperatures in lower light, and the gun includes a Hold function so you don’t have to keep the trigger pulled to read the number.
It also offers a useful range for common scenarios mentioned in the product info, from kitchen cooking surfaces to HVAC-related checks and even activities like soap making. You get a °C/°F switch, plus high/low temperature alarms if you want a more “set expectations and watch the number” approach.
One limitation to keep in mind: the red laser dot is not the exact spot where the temperature is measured. The measured surface is about 2 cm below the laser pointer tip. That doesn’t make it unusable, but it’s the kind of thing that can trip you up the first time you use it—especially if you’re trying to measure a small area very precisely.
Where it fits best (and where it doesn’t)
This thermometer gun is positioned for surface temperature checking. The manufacturer information explicitly notes it is not for measuring body temperature, and it warns against aiming lasers into eyes.
It’s a solid match if you need quick, non-contact readings such as: - Checking whether a griddle or cooking surface is ready before you cook - Monitoring a pizza oven’s surface heat during set-up - Spot-checking heat on non-human surfaces during BBQ use - Supporting tasks like soap making, where consistency can matter - General HVAC-related surface temperature checks (so long as you’re measuring surfaces, not people)
It may not be the best choice if you need guaranteed pinpoint accuracy on tiny targets at long range, because the measurement area depends on distance. The product info includes a distance-to-spot ratio of 12:1 and states you can reach best accuracy up to 14.17 inch (without touching hot objects). If you’re often working with very small or far-away targets, you’ll want to pay closer attention to how far you’re aiming.

What to check before you buy
Infrared thermometers are a bit more “emissivity-aware” than people expect. This model includes adjustable emissivity from 0.10 to 1.00, which is helpful if you’re measuring different materials with different surface properties.
Also, double-check your use-case for non-contact surface temperature reading. If you were hoping for something to measure human skin temperature, this isn’t that tool.
Finally, think about how you’ll interpret the laser: the red dot is there for aiming, but the temperature being measured is around 2 cm below the laser pointer tip. That’s especially important if you’re measuring over grates, uneven surfaces, or anything where a small shift changes what part you’re really sampling.
Is it worth it?
Worth considering if you want a straightforward non-contact surface thermometer gun for cooking and practical heat checks, and you’ll benefit from a quick trigger-read, Hold function, °C/°F switching, and high/low alarms. The stated range (-50°C to 400°C) and the adjustable emissivity make it more flexible than very basic infrared guns.
You may want to skip it if you need extremely tight spot accuracy on small areas from longer distances, or if you’re expecting the laser dot to match the exact measurement point. And of course, if your goal is human body temperature measurement, this is not for that.
Mini FAQ
Can I measure body temperature with this thermometer gun?
No. The product information states it is not for use in measuring body temperature.
Does the laser dot show the exact temperature spot?
Not exactly. The red laser dot is for aiming, but the measured surface is about 2 cm below the laser pointer tip.
How fast is the reading?
It’s described as continuously scanning and giving a surface temperature reading with an error of only ±1.5% in 0.5 seconds.
Does it save the reading after I release the trigger?
Yes. It maintains the last displayed reading when you release the trigger.
What’s included in the box?
The info provided lists the WT313B thermometer gun, 2x AAA batteries, a user manual, a 12-month warranty, and customer service.
