Speed and Accuracy: Testing Both Models
n
For many cooks, the difference between a usable thermometer and a great one comes down to speed and accuracy. To test both:
nn
- n
- Each thermometer was inserted into a vigorously stirred ice bath and boiling water, then into various meats on the grill and stovetop.
- Thermapen consistently stabilized temperature readings in 2–3 seconds.
- ThermoPop required slightly more time, typically stabilizing in 3–4 seconds.
- Both models produced results within their advertised error margins, but the Thermapen was slightly more precise, especially when fine adjustments mattered (e.g., rare steaks).
