Eventek ET312 vs Lasergrip GM400 Infrared Thermometer

Overall Verdict

When comparing the Eventek ET312 and the Lasergrip GM400, it quickly becomes clear which one we recommend based on their accuracy ratings alone. Our benchmark awards the Eventek ET312 with an impressive performance rating of 8.2 out of 10, making it the highest-rated thermometer in our database as of June 2023. In contrast, the Lasergrip GM400 receives a significantly lower rating of only 5.3.

Considering accuracy as the primary factor and not accounting for other aspects like design (in which the Lasergrip GM400 also falls behind the Eventek ET312), the clear choice between these two infrared thermometers is the Eventek ET312. We cannot recommend the Lasergrip GM400 for anyone or any purpose.

Pros & Cons
