This Armpit mercury-free thermometer is a safe, accurate, and environmentally friendly medical device for measuring axillary temperature. It is widely used in homes, clinics, and hospitals, suitable for all ages, especially children and the elderly. It uses a non-toxic gallium indium tin alloy (GaInT) instead of mercury as the thermometric liquid, eliminating mercury-related health and environmental hazards.

Features

1. 100% Mercury-Free: Uses a gallium indium tin (Ga-In-Sn) alloy instead of mercury, ensuring safety and environmental friendliness. No toxic mercury vapor is released upon breakage.

2. High Precision: 37°C point tolerance ±0.1°C, full range 35-42°C meets clinical-grade requirements.

3. Battery-Free: Utilizes the physical expansion principle of a glass capillary tube, eliminating the need for charging or battery replacement; ready to use anytime.

4. Clear Readings: Large scale with yellow/white background; some models include a magnifying glass tube, making reading easy even for the elderly.

5. Portable and Protective: Standard hard plastic casing/storage case, drop-proof and dustproof, approximately Ø5 mm × 120-125 mm in size, weighing only 6-7 g.

6. Easy Disinfection: Simply wipe with alcohol wipes; supports repeated use, with virtually zero cost per measurement.

Instructions for Use (Axillary Mode)

1. Before measurement, check if the temperature column is below 35°C. If it is above this value, hold the top and shake downwards 5-12 times.

2. Wipe the temperature-sensing bulb with an alcohol swab and keep the armpit dry.

3. Place the temperature-sensing bulb completely in the center of the armpit, with the upper arm pressed against the chest wall, and hold for 5-6 minutes.

4. After removing the bulb, rotate it horizontally and read the highest temperature column position against the light.

5. After use, shake it down to below 35°C again, clean it, and store it in the plastic tube.
