Review: Thomson Thermo FH2: A Swift and Simple Forehead Thermometer

Review: Thomson Thermo FH2: A Swift and Simple Forehead Thermometer offers swift and relatively accurate readings, especially considering its user-friendly nature


The Thomson Thermo FH2 is designed for quick and contactless temperature readings, positioning itself as a user-friendly solution for families seeking simplicity and accuracy. With its infrared technology, it not only measures forehead temperatures but also can gauge the temperature of objects, liquids, or foods.

Design and Build

The slender design of the Thomson Thermo FH2 offers easy handling, although the shiny white ABS plastic can be a bit slippery. Constructed with minimal visible screws, it’s relatively easy to maintain. While not waterproof, a simple wipe with a cloth soaked in alcohol suffices for disinfection.

The device is powered by two AAA batteries and boasts an estimated autonomy of 500 measurements. Its non-contact nature makes it less prone to contamination, and the batteries can be accessed by pressing the base of the cover.

User-Friendly Operation

Operating the thermometer is intuitive, with initial measurements being straightforward even without consulting the manual. However, referring to the manual is recommended to ensure proper handling and adjustments as needed. The manual also provides insightful medical information about body temperature variations throughout the day and specifies normal and fever temperature ranges for different measurement types.

For measurements, users need to position the thermometer around 3 to 5 cm from the center of the forehead, just above the eyebrows. An LED above the probe assists with positioning by illuminating the area in blue.

Visual and Memory Features

The device’s screen backlight changes color, with orange indicating a temperature between 37.2°C and 38.2°C, and red signifying a high fever. The thermometer stores the last nine measurements, accessible by pressing the “Mem” button while the device is off.

Accuracy and Speed

The Thermo FH2 impresses with its speed, being ready in just 2 seconds and providing measurements within a second. The quick interval between measurements allows for persistence in monitoring temperature changes.

Positioning accuracy is essential, as deviations of nearly 20% can occur when measurements stray from the ideal point on the forehead. The Thermo FH2 shows good precision overall, effectively capturing fluctuations in body temperature.

Considerations and Conclusion

While the frontal measurement from the forehead is convenient, it’s worth noting that it may not be as reliable as other methods due to variations in skin condition and external factors. For precise measurements, taking the temperature at the temple is recommended.

In conclusion, the Thomson Thermo FH2 offers swift and relatively accurate readings, especially considering its user-friendly nature. Its color-coded fever indications add to its family-oriented appeal, making it a dependable option for quick temperature checks.
