## Summary description

Digital infrared thermometer Dr. Senst DET-20F provides 3‑in‑1 measurement modes for ear, forehead and object temperatures. The contactless forehead and object modes enable quick, hygienic readings while the ear mode offers accurate body measurements. Suitable for home and clinical use to monitor fever, check liquids or surfaces, and support fast decision-making.

## Long description

The Dr. Senst DET-20F digital infrared thermometer offers three measurement modes—ear, forehead and object—designed for fast and hygienic temperature checks. Contactless forehead and object modes allow rapid screening without skin contact, while the ear mode provides direct body temperature readings. Compact and lightweight, this device is suitable for both household monitoring and clinical environments where quick, repeatable measurements are required.
Advantages
The thermometer combines infrared sensors with an easy-to-read digital display to deliver prompt results. Dual-mode operation supports contactless measurements for reduced cross-contamination and a probe-based ear mode for precise core temperature detection. Built-in memory and an intuitive button layout simplify repeated measurements, and an automatic backlight makes readings clear in low-light conditions.
Suitable for
Home fever monitoring for adults and children
Quick screening of foreheads in public or clinical settings
Measuring temperature of liquids and surfaces without contact
Childcare settings and pediatric checks
Everyday use for monitoring health changes and treatment responses

How to use
To take a forehead or object temperature, point the thermometer at the center of the forehead or the surface of the object from the recommended distance and press the measurement button; wait for the audible or visual signal before reading the display. For ear temperature, gently insert the probe tip into the ear canal following the angle recommended in the user manual and activate a measurement. Allow the device to stabilize between measurements if multiple readings are needed and consult the manual for environmental conditions that can affect infrared readings.
Usage recommendations
Use the ear mode for the most accurate core body temperature and the forehead mode for non-contact screening. Ensure the forehead is dry and free of sweat or coverings when measuring; avoid taking readings immediately after exposure to extreme temperatures. For object or liquid temperature checks, measure at a consistent distance and follow hygiene practices between uses. Refer to the supplied manual for maintenance, calibration advice, and safety instructions.
