MESTEK Infrared Thermometer Gun - Accurate Non Contact Laser

In this review the MESTEK Infrared Thermometer Gun comes across as a versatile tool for home DIYers, cooks and light industrial users who need quick surface temperature checks without contact. The single biggest reason to buy is the combination of non contact laser measurement with a K-type probe and adjustable emissivity, which together let the user measure awkward, hot or food surfaces more reliably than a simple IR gun alone. It reads fast, shows ambient humidity and dew point, and the bright color display makes readings easy to confirm.

Key Features

• Dual measurement modes: Built-in non contact infrared and included K-type probe allow surface and interior temperature checks for a wider range of tasks.
• Adjustable emissivity: Emissivity from 0.1 to 1.0 helps improve accuracy on different materials like metal, wood or painted surfaces.
• Longer distance targeting: The 12:1 distance to spot ratio and 13 point laser guidance make it practical to measure harder to reach or hot objects safely from a distance.
• Useful environmental readings: The French HTU20 sensor reports ambient temperature, humidity and dew point alongside surface values to help interpret results.
• Clear visual feedback: A colorful VA display with backlight, unit switch and max/hold makes it easy to read in low light and capture transient values.
• Alarm modes: Spoilage and temperature difference alarms help identify mold risk or abnormal surface to ambient deltas for troubleshooting.

Who It's For

The thermometer is a solid pick for hobbyists who cook, BBQ or homebrew and need accurate surface or core checks using the K probe, and for household maintenance and light shop work where distance measurement keeps hands safe. Its humidity and dew point readouts also make it useful for gardeners and wine makers checking storage conditions.

Professionals who need laboratory grade traceable calibration or continuous monitoring should look elsewhere; while the gun claims high accuracy it is intended for spot checks and fast troubleshooting rather than precision metrology or medical use for humans or animals.

Pros & Cons

Pros

• Combination of infrared and K-type probe covers surface and interior checks in one tool.
• Adjustable emissivity and 13 point laser guidance improve real world measurement reliability.
• Color display, backlight and quick response time make readings easy to capture and interpret.

Cons

• Surface readings can vary by several degrees depending on emissivity and technique, so some users report mixed accuracy on reflective surfaces.

Our Verdict

The MESTEK Infrared Thermometer Gun is a practical multi purpose tool for cooks, DIYers and light industrial use thanks to its dual measurement modes, adjustable emissivity and environmental readings. It offers strong value for spot checks and troubleshooting when accuracy to within a few degrees is sufficient, though users should allow for surface variability on reflective materials and follow emissivity adjustments for best results.

Frequently Asked Questions

Can this thermometer measure internal food temperature?
The included K-type probe lets you take contact interior readings, while the infrared mode measures surface temperature only.

Is it suitable for measuring very hot surfaces?
Yes, the gun measures up to 1472F (800C) and the 12:1 ratio helps keep distance from hot or hard to reach objects.

Does it measure humidity and dew point?
Yes, the built-in HTU20 sensor displays ambient temperature, humidity and dew point alongside surface measurements.
