The Best Instant-Read Thermometers for Accurate Cooking
Instant-read thermometers are a crucial tool for cooks, helping to avoid over- or undercooking. We tested 24 thermometers to find the fastest and most accurate ones.

Instant-read thermometers are a must-have for any serious cook. They help to ensure that food is cooked to a safe temperature, and can make all the difference in achieving perfect doneness. With so many options available, it can be difficult to choose the right one.
How Instant-Read Thermometers Work
Instant-read thermometers work by using a temperature sensor to measure the heat of a piece of meat or other food. The sensor can be one of several types, including thermocouples, thermistors, and Resistance Temperature Detectors (RTD). These sensors measure the change in temperature and display it on the screen.
Testing the Thermometers
We tested 24 instant-read thermometers to find the fastest and most accurate ones. Our tests included a sous vide water bath, ice water, boiling water, and a roast chicken. We also evaluated the usability of each thermometer, including the ease of reading the screen and the comfort of holding it.
The results of our tests are shown in the following table:
| Thermometer | Response Time | Accuracy |
|---|---|---|
| ThermoWorks Thermapen Nano | 0.4 seconds | ±0.5 °F |
| Lavatools Javelin Pro Duo | 4-5 seconds | ±1 °F |
| OXO Thermocouple | 2-3 seconds | ±1 °F |
| Inkbird | 2-3 seconds | ±2 °F |
| Greenpan AccuRead | 2-3 seconds | ±2 °F |
| ThermoWorks ThermoPop 2 | 2-3 seconds | ±1 °F |
