What is body temperature definition
Temperature is basically presence of thermal energy. More the thermal
energy more heat will be inside, on other hand less thermal energy will have no
heat or cooler it is. The question is how to measure the presence of heat in
the body? The answer is simple and that is through Thermometer[1].
In earlier days many scientist did research to measure the heat or thermal energy in the body on some scale to quantify it. Main scales which were developed are Celsius or centigrade and other one is Fahrenheit.
The Celsius scale is commonly used in world to measure the temperature. According to this scale, the water starts freezing when the temperature fall below 4°C and reaches at 0°C. At 100 °C the water starts boiling.
Similarly, according to Fahrenheit scale the water freezes at 32 °F and boils at 212 °F. Fahrenheit scale is mostly used in American continent. The normal temperature of human should be 98.6 °F[2].
Thermometer is an instrument which
measures temperature i.e degree of heat. The Thermometer records temperature of
body, object or any surface. Thermometer are commonly used everywhere at homes,
hospitals, industries and many other places. Their use at homes has increased
in many forms.
What is digital thermometer
These measure temperature of body through orally
and used by babies, children and adults. In today’s life, digital thermometers
have taken over traditional mercury filled glass tube thermometers. Thermometers normally have silver nib
at one end.
These types of thermometers are only used to record temperature of
human body instead any other object like infrared digital thermometers. Thermometers
with nib allow to measure temperature orally or armpit. It contains bulb
containing mercury which expands and contracts based on the temperature of
body.
LCD is provided to read temperature easily. The accuracy of instruments
varies with the manufacture and is generally 0.1 to 0.3 degree Fahrenheit[3].
The digital thermometers are equipped with many features such as temperature readings in Fahrenheit and Celsius, memory to store more than 30 readings for follow-up, fever alarm, color display, Indicate temperature with sound, one button easy operation and auto power off function to prolong battery life[4]
What is forehead thermometer
The temperature of human is also
measured through its forehead or ear. It can be easily obtained through infrared
digital thermometers. Forehead/Ear thermometers normally come as non-contact
digital thermometers. These thermometers used infrared technology.
The probe of
these thermometers is equipped with sensor. When directed towards forehead/ear, the
temperature of human is recorded. There is significant space about 3 to 5 cm
must be maintained to obtain accurate temperature reading in case of forehead reading.
The accuracy of
instruments varies with the manufacture and is generally between 0.1-0.3
degree Fahrenheit.
The digital thermometers are equipped
with many features such as record temperature through Ear, forehead, Armpit and
Oral, memory function.
It record temperature of more than 30 readings, beep function
to show status of instrument, mute function to silent the process while recording
temperature for babies while sleeping, color display for easy reading, fever Alarm
on high temperature, temperature indications through different colored display
for normal and cautious temperature and record temperature of any object such
as room, liquid and any surface[6].
What is room thermostat
A thermostat is a device which senses the temperature and
regulates it based on the pre set requirements. Thermostats are commonly used
in heating and cooling instruments to achieve desired degree.
Thermostats are
used in homes with built in functions of air conditioners, Oven, Water heaters,
Refrigerators. On other hand they are commercially used in Cold storage,
Offices and factories and many other places.
Most of common features of thermostats are voice controlled, touch
screen with colored display, programmable, wifi enabled, can be used with app
like IOS and Android, used with Alexa, change Screen color, energy saving modes
and password protected.
What is hygrometer thermometer
Hygrometer is a device used to measure water content in any
atmosphere. The water content in any atmosphere depends primarily on
temperature and pressure.
The temperature
is directly involved in amount of water content in such a way that higher the
temperature higher water content will be present in atmosphere. The same goes
in other way as well.
Digital Hygrometers are commonly used in our daily lives either at
our homes or at workplaces. Hygrometers are equipped with many features which show
temperature and humidity of room or place as both are interconnected with each
other.
The main features of hygrometers are used as humidity meter, inform air
conditions status i.e temperature of room or place, capable of storing readings
up to 2 years, wifi enabled, iOS & Android compatible, measure pressure,
show time, weather forecasting and measuring humidity of individual places
within specified perimeter.
