MiniScience supply a large variety of digital
and analog thermometers for different applications. We can also custom produce
thermometers with specific sizes and temperature ranges for your large
The four main different types of thermometers we
Digital Thermometers use a Thermistor or a
thermocouple to measure the temperature.
The most popular style of digital thermometer features a thermistor, a thermally
sensitive object (thermal resistor) about the size of a head of a pin that is
located in the thermometer's tip. Thermisteos exhibit 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.
Thermocouple technology is used in some digital thermometers for faster response
to a temperature change, as well as 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.
|All digital thermometers have easy to
read LCD displays. In many models the sensor is a separate module that
is connected to the display via a cable.
Certain models of digital thermometers
can also be installed on control panels and on the external shell of
machinery. In this way you can continuously read the temperature of
specific spots in a machine from outside. You can also install these
thermometers in your car or in your room to read the outside

2. Glass thermometers
|Glass thermometers consists of a bulb
containing some liquid (mercury, alcohol, spirit) attached to a glass
tube of narrow diameter. The changes in the
temperature results the expansion or contraction of the liquid and the
level of the liquid in the glass column. The glass column may be marked
based on Celsius or Fahrenheit from outside.
Glass thermometers are most commonly used
in laboratories where they come in contact with corrosive chemicals.
They are easy to use and chemists tend to use them occasionally as
stirring rods too.
Glass thermometers are made with
different liquids, different ranges and different accuracy levels.
MiniScience supply the most widely used
ranges of thermometers for research and educational laboratories.

3. Dial thermometers or
|Dial (or bimetal) thermometers are
durable, inexpensive and can be made for a wide range of temperatures.
We carry two types of dial thermometers. The thermometers with a stem
have their sensor inside the stem so that you can be inserted in ovens,
liquids or soft solid materials such as cakes, meat, turkey, juices and
syrups. The dial thermometers without the stem are usually mounted on
the walls or placed on the desk as room thermometers.
See all Dial Thermometers
A bimetal strip can be wound in the shape
of a coil, similar to the mainspring of a clock. In this shape the coil will
wind, or unwind, as the temperature changes. If one end of the coil is held so
that it cannot move, the other end will be free to move. A pointer is attached
to the free end, and the temperature registers on the dial beneath the pointer.
