Intended Use

The infrared thermometer is intended for the intermittent measurement of body temperature from the auditory canal or central forehead skin surface on people of all ages. It can be used by consumers in the household environment and by healthcare providers.

Device Story

HT series infrared thermometers (HT-101, HT-102, HT-103, HT-104) measure body temperature by capturing infrared energy radiation from the ear or forehead. The device uses a Fresnel lens to focus infrared energy onto a thermopile sensor. A signal receiving processor converts the input into a temperature reading, displayed on an LCD. Features include automatic range selection, 35-measurement memory, high-temperature alarm (color-coded backlight), and mute/un-mute functionality. Powered by 2 AAA batteries. Used by consumers in household environments or by healthcare providers. The output provides immediate temperature readings to assist in clinical decision-making regarding fever management. Benefits include non-invasive, rapid (1-second) temperature assessment.

Clinical Evidence

Clinical accuracy validation conducted per ASTM E1965-98(2016) on 150 subjects (50 infants, 50 children, 50 adults). Results confirmed the device met requirements for clinical bias and clinical repeatability.

Technological Characteristics

Thermopile-based infrared sensor; Fresnel lens; LCD display; powered by 2x1.5V AAA batteries; IP22 ingress protection; Type BF applied part. Materials: ABS/PA757, PC/PC-110. Standards: ISO 80601-2-56, ASTM E1965-98, IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, ISO 10993-5, ISO 10993-10.

Indications for Use

Indicated for intermittent body temperature measurement via auditory canal or central forehead skin surface for all ages, including infants, children, and adults. Suitable for household and clinical use.

Regulatory Classification

Identification
