Wintact WT530 vs Smart Sensor AS530 Infrared Thermometer

Overall Verdict

The Wintact WT530 stands out as one of the best-performing infrared thermometers in our database. As a result, it easily surpasses the Smart Sensor AS530.

In terms of performance, our benchmark awards the Wintact WT530 an impressive 8.0 out of 10 score. On the other hand, the Smart Sensor AS530 disappoints with a lackluster total score of 4.8, primarily due to its underperformance in the cold test involving ice. When it comes to accuracy, you can expect significantly better results from the Wintact WT530 compared to the Smart Sensor AS530.

Even without considering other factors, such as design and usability, it's evident that we cannot recommend the Smart Sensor AS530 over the Wintact WT530. The latter provides far better value for your money and outperforms the Smart Sensor AS530 in multiple aspects.
