BODY TEMPERATURE
• Body temperature varies from person to person and fluctuates during the course
of the day. For this reason, it is suggested to know one's normal, healthy forehead
temperature to correctly determine the temperature.
• Body temperature runs approximately from 35.5°C to 37.8°C (95.9°F-100°F). To
determine if one has a fever, compare the temperature detected with the person's
normal temperature. A rise over the reference body temperature of 1°C (1°F) or more
is generally indication of fever.
• Different measurement sites (rectal, axillary, oral, frontal, auricular) will give
different readings. Therefore it is wrong to compare the measurement taken from
different sites.
• Here below are typical temperatures for adults, based on different measurement
sites:
Rectal: 36.6°C to 38°C /97.9°F-99.1°F
Axillary: 34.7°C to 37.3°C /94.5°F-99.1°F
ASTM laboratory accuracy requirements in the display range of 37°C (98°F to 102°F)
for IR thermometers is ±0.2.(±0.4°F), whereas for mercury in-glass and electronic
thermometers, the requirement per ASTM Standards E667-86 and E1112-86 is
±0.1.(±0.2°F).
Caution: This infrared thermometer meets requirements established in ASTM Standard
(E1965-98) Except of clause 5.2.2. It displays subject's temperature over a range of
34.0°C ~43.0°C. Full responsibility for the conformance of this product to the standard
is assumed by (Hetaida Technology Co., Ltd. Add: 4F, Baishida High-Tech Park, Xiandong
