Fast & Accurate Fever Thermometer

The FDK Digital Thermometer delivers precise temperature readings within seconds, making it suitable for adults, kids, and babies. Its flexible tip ensures comfortable use for oral, underarm, or rectal measurement. The device includes dual-language support in English and Spanish for accessible operation. It is fully waterproof, allowing direct rinsing under running water or cleaning with alcohol.

Sustained-Use Behaviour

The thermometer stores the last reading to help track fever patterns over time, supporting ongoing health monitoring. An automatic shutoff function activates to conserve battery life between repeated uses. Power is supplied by two CR2025 3.0V batteries, rated for approximately 3,000 to 5,000 measurements during the device's service life. The unit switches between Celsius and Fahrenheit by holding the power button for 12 seconds.

Thermals, Noise & Power Draw

The large LCD screen uses a dual-colour backlight, displaying normal temperatures in blue and switching to red when a reading exceeds 100.0°F (37.8°C). This visual alert provides immediate fever indication without audible alarms unless the voice function is enabled. The device operates silently during measurement and has no moving parts or active cooling. Battery consumption remains minimal due to the auto-shutoff feature.
