Smart Sensor AS530 vs. Mecurate IRT600A Digital Infrared Thermometer

Overall Verdict

Finding the better option in this pair is not difficult, but there is one unfortunate reason: the Smart Sensor AS530 fell short of our expectations. If you must choose between the two, the Mecurate is the clear winner.

The Smart Sensor AS530 received the lowest scores in our performance test. In the cold test with ice, it achieved a disappointing score of 2.65 out of 10. Even in the hot test, it barely scraped by, scoring 6.17 out of 10. With an overall performance rating of only 4.8, it fails to meet our standards.

The Mecurate IRT600A, on the other hand, passed both tests and received a total performance score of 6.9 out of 10.

Consequently, if you require high precision from your IR thermometer, the Smart Sensor AS530 is not the one that will provide it.

Both models fare reasonably well in terms of design.

However, regarding usability, the Smart Sensor AS530 suffers due to its lack of extra measurement modes. As a result, its usability score plummets to just 5.85 out of 10. In contrast, the Mecurate offers three different modes for users to choose from and easily pass this criterion.

Pros & Cons

  • Well-built and rugged design
  • Textured handgrip for easier handling when hands are wet
  • Tactile trigger
  • Very bright laser emitter
  • Solid build quality.
  • Has several measurement modes.
  • Practical laser emitter with 13-point patterning.
  • Easy to handle with a clicky, tactile trigger.
  • Bright, colored VA display panel.
  • Comes bundled with a meat thermometer
  • Bad measurement accuracy
  • Doesn’t come with extra measuring modes
  • Unreliable readings. Multiple continuous scans are required before the thermometer “re-calibrates” itself and output more accurate results.
