Wintact WT530 vs Lasergrip GM400 Infrared Thermometer

Overall Verdict

When comparing the Wintact WT530 and the Lasergrip GM400, it becomes evident right away that the former is the superior choice overall, especially when considering the performance score. The Wintact WT530 received a solid score of 8.0, while the Lasergrip GM400 struggled greatly in our performance tests, receiving a score of only 5.3, mainly due to underperformance in the cold test involving ice.

In terms of design and usability, the Lasergrip GM400 also falls behind the Wintact WT530. It has lower build quality, a less bright display, and a laser emitter that is less impressive than the Wintact WT530. Our reviewers also noted that the Lasergrip GM400 lacks any additional measurement modes, which is a significant drawback compared to the Wintact WT530's four modes.

Overall, the Wintact WT530 emerges as a much more compelling and superior choice in various aspects.
