1. PRODUCT DESCRIPTION
Dr Trust Homedoc Ear and Forehead Thermometer is a dual temperature
mode (°F / °C) thermometer. It measures the body temperature based on
detecting 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 on the forehead. The operation of this
thermometer is very simple. It can be operated through a power button that
is present on the top of the device just below the large size LED screen. The
LED screen displays measurements in large size digits which are easy to read
even in dark conditions. Also, there are 3 colour codes to indicate different
temperatures of fever.
1.1. Introduction
over 3 months old.
Note:
Ear temperature measurement can only be applied to people who are
At the end of the temperature measurement, the buzzer gives a ‘beep’
cue.
1.2. Normal Body Temperature Range
Normal body temperature has a range. The following table shows that this
normal range also varies by measuring different sites. Therefore, readings
from different site should not be directly compared. Tell your doctor what
type of thermometer you have used and what part of body you have
measured. Also keep this in mind if you are diagnosing yourself.
1.3. Intended Use
The multifunctional infrared thermometer is intended for measuring the
human body temperature, it has two measurement modes;
The forehead mode: Indicated for people of all ages.
The ear mode: Indicated for people above three months old.
2. WORKING PRINCIPLE
The Dr Trust Homedoc Ear and Forehead Thermometer is intended for the
measurement of human body temperature. Its sensor collects infrared
energy emitted by the eardrum in the ear canal or the skin of forehead. After
being focused by a lens, the infrared energy is converted into a temperature
reading by the thermopiles and measurement circuits.
mode is indicated for people above three months old.
The forehead mode is indicated for people of all ages and the eardrum
