Digital Thermometers
Digital thermometers use a Thermistor or a Thermocouple
to measure the temperature.
Digital Thermometer DTC120
DTC120 is a digital thermometer with external
sensor for accurate measurement of temperature inside devices (such as
refrigerator, computer, ...) or outside the room. The sensor is connected to the
display unit via a 3-feet (90 cm) long cable.
It can be mounted/ inserted in
different ways. Has large, easy-to-read display.
You may mount DTC120 inside the
automobile so that it can read the outside temperature. Mount it in your
bedroom near the window or on the window frame so that you can read
outside temperature. Many people call this a refrigerator thermometer
because they mount it on the refrigerator so that it can read the
temperature inside. |

Digital Thermometer and
Hygrometer HC520
This multi-function device can measure
the humidity, as well as inside and outside temperature. It can be
placed on a desk or hung on the wall.
Think of it as your personal weather
station or a convenient weather reporting device. One temperature sensor
and one humidity sensor are inside the device. An external temperature
sensor is connected via a 4-feet long wire. In order to read both the
inside and the outside temperature, place or hang your thermometer near
a window so that the external sensor can reach outside. In this way the
internal temperature sensor measures the temperature at its current
location and the external sensor measures the outside temperature. |

Digital
Thermometer Technology
There are two electronic components that can be
used as a sensor in making digital thermometers. One is a thermistor (Thermal
Resistor) and the other is thermocouple.
Digital Thermometers using a
Thermistor
The most
popular
style of
digital
thermometer
features a
thermistor,
a thermally
sensitive
object about
the size of
a head of a
pin that is
located in
the
thermometer's
tip. It
exhibits a
change in
electrical
resistance
with a
change in
its
temperature.
The
resistance
is measured
by passing a
small,
measured
direct
current (dc)
through it
and
measuring
the voltage
drop
produced.
Digital
thermometers
using a
thermistor
usually
provide an
accurate and
stable
response in
6-8 seconds.
Digital
Thermometers
using a
Thermocouple
Thermocouple
technology
makes these
digital
thermometers
the fastest
on the
market,
showing
temperature
readings in
about 2 - 5 seconds,
with high
accuracy and
a high
temperature
range.
Because of
this,
thermocouple
digital
thermometers
are by far
the mostly
widely used
for
industrial
and
foodservice
purposes.
Thermocouple
digital
thermometers
are designed
to check for
final
cooking
temperatures.
Because of
their speed,
they can be
used to
quickly
check
temperature
in a number
of places,
which is
especially
helpful with
large food
items such
as turkeys
or roasts.
Their thin
probe also
facilitates
use with
thin foods
such as
hamburgers
and pork
chops.
The
thermocouple
is a device
that
generates
electricity
when heat is
applied to
its tip. It
consists of
two
different
types of
metal wires
that are
both
electrical
conductors,
joined
together at
one end and
connected to
a
voltage-measuring
device at
the other
end. When
the junction
of the two
metals is
heated or
cooled, a
voltage is
created that
can be
correlated
to
temperature.
Thermocouples
are
available in
different
combinations
of metals or
calibrations.
The most
common
calibrations
are J, K, T,
and E, each
of which
measures a
different
temperature
range. The
maximum
temperature
changes with
the diameter
of the wire
used.
