This lightweight non-contact thermometer supports 1s fast reading, dual measurement modes and wireless data sync. It delivers precise results, stores 32 records, features unit switch, HD LCD and runs on two AAA batteries.
The infrared sensor receives infrared energy emitted from the forehead or object surface, converts it into an electrical signal, calibrates it via an algorithm, and wirelessly transmits the data to a smart device via Bluetooth, NB‑IoT, or Wi‑Fi.
After each use – Wipe the probe and housing surface with a dry soft cloth to keep clean.
Probe cleaning – If dirty, gently wipe the probe lens with a cotton swab moistened with 75% medical alcohol; air dry. Do not rinse or submerge in water.
Do not touch the probe lens – Scratches from fingers or hard objects may cause measurement errors.
Battery replacement – Uses two AAA alkaline batteries; observe correct polarity. Remove batteries if not used for long periods to prevent leakage and corrosion.
Storage conditions – Store in a dry, cool place (10°C–40°C) away from high temperature, humidity, direct sunlight, and dust.
Usage notes – Forehead should be clean, dry, and free of sweat, cosmetics, or obstruction before measurement. If ambient temperature changes drastically, allow the device to stabilize for 10–15 minutes before use.
Wireless connection maintenance – If Bluetooth/Wi‑Fi/NB‑IoT connection is unstable, try re‑pairing or checking the network signal.
