Lasergrip GM400 vs Mecurate IRT600A Digital Infrared Thermometer Side-by-Side Comparison

Lasergrip GM400 vs Mecurate IRT600A Digital Infrared Thermometer

Overall Verdict

From the get-go, it's evident that the Mecurate IRT600A is the superior choice when comparing these two IR thermometers.

In our performance test, the Lasergrip GM400 fell flat in the cold test, scoring a meager 2.9 out of 10. It fared slightly better in the hot test, achieving a score of 5.6. However, the damage was already done to its total performance score, with the Lasergrip GM400 earning a lackluster 5.3 out of 10. While that is a passing score in our testing methodology, it doesn't hold up well against the other IR thermometers on our list, like the Mecurate IRT600A.

The Mecurate IRT600A performed decently in both performance tests, receiving an overall performance score of 6.9 out of 10.

In terms of design, both models were acceptable, but the Mecurate IRT600A outshined the Lasergrip GM400 with a design score of 9.5, compared to the latter's 6.1 out of 10. The lower score for the Lasergrip GM400 can be attributed to its subpar build quality, characterized by lightweight and cheap-feeling plastic details. Notably, the laser emitter is very dim to the point of being hard to use.

The usability section was where the Lasergrip GM400 completely fell apart. With no extra measurement mode and a bad speaker, it earned a dismal score of 4.3 out of 10.

In summary, if you're seeking an exceptional thermometer overall, the Mecurate IRT600A is the clear winner. We cannot recommend the Lasergrip GM400 for any application, as it falls short in several crucial areas.
