DIGITAL THERMOMETER 1`s

This Digital Clinical Thermometer uses a precision negative temperature coefficient (NTC) thermistor sensor to accurately measure body temperature. The sensor's resistance changes predictably with temperature; the microprocessor converts this resistance to a digital reading displayed on the large LCD screen within 60 seconds.

Features include: audible completion beep when a stable reading is achieved, last-reading memory recall, automatic power-off to conserve battery, and a waterproof probe tip for safe cleaning with alcohol wipes between uses.

Measurement Routes & Normal Ranges

• Oral (sublingual): 36.4–37.4°C — most practical for adults and children ≥5 years

• Axillary (underarm): 35.9–36.9°C — approximately 0.3–0.5°C below true core temperature

• Rectal: 36.6–38.0°C — most accurate, recommended for infants under 3 years (insert only 1–2 cm)

Fever threshold: oral >37.5°C; axillary >37.2°C; rectal >38.0°C.

Technical Specifications

• Accuracy: ±0.1°C within the clinically relevant range of 35–43°C

• Battery: LR41 (AG3) button cell — included

• Protective storage case included

• Complies with CE and ISO 13485:2016 standards

Safety & Maintenance

• Clean probe with an alcohol wipe before and after each use.

• Do not immerse the full device in liquid — the probe tip only is waterproof.

• For rectal use in infants, apply a small amount of lubricant and insert only 1–2 cm.
