One of the least expensive temp gun units in the market yet equally effective in giving you accurate temperature readings is this temperature gun from HOLDPEAK. The 981C comes with the same temperature range that most of the other infrared temperature gun products in this list come with at minus-58 degrees to 1022 degrees Fahrenheit. Its emissivity is also fully adjustable to allow for temperature compensation and ensuring a more reliable reading, although its +/-1% accuracy is more than enough guarantee.
The 981C comes with a smaller profile, perfect for including in your toolbox for storage right in your trunk. The display comes in a bright green LED which is quite unusual since most of the units available in the market come with either the soft white or the blue LED. At least, green is way cooler to the eyes, allowing you to continue your work without really complaining about eye strain.
