Temp Guns, or Infrared Thermometers, are one of those tools that used to be super expensive and then a few years ago you started seeing them at places like Harbor Freight for cheap. And whether you were using them to check exhaust port temps, water temps, track temp, or whatever, they did the job. But that means different things for different people. In the world of measuring, whether it is dimensions, temps, or clearances, people often don’t understand the importance, or lack thereof, when it comes to accuracy. For example: Let’s say I have a cheap temp gun that I have zero clue as to how accurate it is. Does it matter? Well, it depends on how I’m using it. If I use it to see if one cylinder on my engine is not firing, then I don’t care about accuracy because while 7 of them will be 500+ degrees, the one dead hole will only be around 250. Whether those numbers are accurate, doesn’t matter. All that matters is that I can tell which one is colder than the other.

Same goes for a tape measure. The increments, units of measure, etc are of no importance at all for anything I do in my own shop. I could use a piece of string and make marks on it to know how long something needs to be cut. The only time the number matters is if I am telling someone else what to cut a piece to, and they don’t have access to my string.

See what I mean?

But some tools need to be accurate! If you are measuring voltage and want specifics, you want accuracy. If you are measuring track temp, you want accuracy. Or more specifically repeatability. If you temp gun says 125, when the actual temp is 130, that doesn’t matter as long as it reads consistently so you can log track temps. But lets say you want to be as accurate as possible with a temp gun. Can you afford to buy a cheap one at that point? Or is the expensive one actually worth more money? Does the name brand just make you feel better, or does it actually perform better?

Let’s see!

Fluke, Milwaukee, Klein Tools, AMES, VEVOR, NJTY T600, Sovarcate, AOPUTTRIVER, KIZEN, Surpeer, MESTEK, ThermoPro, and Soonkoda. Infrared thermometers compared for performance at various temperatures and on various types of surfaces.

The infrared thermometers were also compared for display visibility in direct sunlight and speed at measuring temperature. I purchased all of the infrared thermometers and supplies used to test the thermometers to ensure an unbiased review. So, thank you for supporting the channel!
