Thermometers

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 manufacturing projects. 

The four main different types of thermometers we carry are:

1. Digital thermometers

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 temperature.

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 bimetal thermometers

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.

 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.

 4. Infrared thermometers (Non-contact thermometers)

These specialized thermometers can quickly measure the surface temperature of an object without touching it. Infrared thermometers are used to measure surface temperatures only, not internal temperature. Because they operate remotely, they are helpful when it is not possible or practical to physically contact the object being measured (which may be very hot, small or distant). Remote operation also eliminates any possibility of cross-contamination. This technology uses infrared light rays (between microwave and ultraviolet radiation) to measure the temperature. All objects give off radiation (emissivity).

IR Thermometers provide fast and accurate surface temperature measurement. They do not do well measuring shiny surfaces or gold.
