Helect Infrared Thermometer Gun vs ThermoPro TP-30 Digital Side-by-Side Comparison

The Helect IR thermometer has been found by our reviewers to be one of the most accurate out of all the models we’ve tested. So, it’s not surprising that it turned out to perform better than the ThermoPro TP-30 in terms of accuracy. But if you’re looking for a cheaper deal, the ThermoPro TP-30 isn’t half-bad!

Besides having fairly decent accuracy, the Helect thermometer also stands out for its ergonomic design and ease of use. This model should be a good companion both in the kitchen as well as outside, ready to help you with any temperature-measuring application.

On the other hand, the ThermoPro TP-30, while offering a similar set of functionalities, has far more limited accuracy than the Helect, according to our testing, particularly in high-temperature scenarios like measuring the temperature of a hot pan of oil. Our reviewers have also noted the ThermoPro TP-30 to have fairly mediocre build quality and design.

If precision and ergonomics are your priorities, the Helect H1020 would be the better choice. The ThermoPro TP-30, despite its shortcomings, could still be a viable option for basic kitchen use where extreme accuracy isn't as critical.
