Product Description
1)
Overview
Infrared Thermometer JPD-FR300 measures the body temperature based
on the infrared energy emitted from the eardrum or the forehead. Users can
quickly get measurement results after positioning properly the temperature
probe in the ear canal or forehead.It can also be used to measure the
surface temperature of object.(such as milk and water)
2)
Structure
The thermometer consists of a shell, an LCD, a measure button, a beeper,
an infrared temperature sensor, and a Microprocessor.
3)
Operating principle
The infrared temperature sensor collects infrared energy emitted by the
eardrum or the skin surface. After being focused by a lens, the energy is
converted into a temperature reading by the thermopiles and measurement
circuits.
Normal body temperature
fluctuates throughout the day
and is also affected by external
factors.The body temperature of
an individual is the lowest
between 2:00 a.m. and 4:00 a.m.
and the highest between 2:00
p.m. and 8:00 p.m. An
individual's body temperature
typically changes by less than
1°C (1.8°F) each day.
