10 Best thermometers 2025 in the United States

The ThermoWorks Thermapen ONE is an instant-read thermometer that shines with its impressive speed and accuracy, delivering temperature readings in just one second with precision to ±0.5°F. This makes it ideal for anyone needing quick results, such as chefs or home cooks aiming for perfect culinary outcomes. Its superior usability, including a 360-degree auto-rotating display and motion-sensing activation, ensures ease of use regardless of lighting or hand orientation, which is a thoughtful design aspect. The thermometer is also waterproof, boasting an IP67 rating, meaning it can withstand splashes and is easy to clean, though it's recommended for hand wash only.

Durability is a strong point with its commercial-grade construction backed by a 5-year warranty, making it a reliable choice for daily use in demanding environments. The inclusion of a NIST-traceable calibration certificate is a testament to its precise accuracy. However, it lacks a memory function, so it doesn’t store previous readings, which could be a downside for users who need to track temperature trends over time. On the hygiene front, while its durable construction allows for easy cleaning, users must adhere to hand washing instructions.

Powered by a single AAA battery, it remains convenient and portable. Certified by multiple safety standards, including NSF, CE, and RoHS, users can feel confident about its food safety credentials. Its striking Cayenne Pepper Red color adds a touch of style, though this is more a cosmetic benefit than a functional one. The Thermapen ONE is well-suited for those prioritizing speed, accuracy, and reliability in a thermometer, particularly in professional or home cooking settings.

The Frida Baby Thermometer is a versatile 3-in-1 infrared thermometer, which makes it a great choice for families with infants, toddlers, and even adults. One of its standout features is the rapid measurement speed, providing accurate temperature readings in just one second. This is incredibly helpful for parents who need to quickly assess their child's temperature, especially during times of illness. The thermometer can be used in three different ways—ear, forehead, and touchless measurements—making it adaptable to various situations, including monitoring room or bottle temperatures.

Ease of use is another strength, thanks to its color-coded screen and sound alerts that simplify the process of reading temperatures, allowing parents to easily identify when a fever might be present. Moreover, the ability to store up to 40 previous readings is a fantastic feature for tracking health changes over time, giving parents a clearer picture of their child's health trends.

On the flip side, some users may find the reliance on batteries a minor inconvenience, especially when they run out unexpectedly. While it does come with a storage pouch for easy portability, the outer plastic material might not feel as durable compared to thermometers made from higher-grade materials. Cleaning is straightforward, as it only requires a wipe-down, but it’s crucial to handle it carefully to maintain its functionality. Additionally, while the thermometer is designed mainly for kids, adults can also use it, making it a family-friendly option.

The ThermoWorks RFX is a smart wireless meat thermometer designed for serious home cooks and BBQ enthusiasts who want precise, hassle-free temperature monitoring. It stands out with its use of radio frequency and Wi-Fi connectivity, offering a much stronger and more reliable signal than common Bluetooth models. This means you can monitor your meat from up to 1,500 feet away or even farther via Wi-Fi, giving you freedom to entertain or prep without needing to stay near the grill or smoker.

Its accuracy is impressive, with sensors pinpointing internal meat temperature within ±0.9°F, helping you cook meats perfectly every time—whether steaks, briskets, or ribs. The device is easy to use, featuring a digital display and a quick 10-minute charge that lasts over 50 hours, so it’s ready for both quick grills and long smoking sessions. It also has a memory function that uploads your cooking data to the ThermoWorks Cloud, making it easy to track and improve your recipes over time. Cleaning and durability are straightforward as the probes are built for outdoor use and consistent performance.

One downside is the need for charging multiple lithium-ion batteries and setting up the gateway device, which might feel a bit technical for some users. For those seeking a dependable, high-performance thermometer that maintains a strong connection without interruption, the RFX offers a reliable solution.
