In today's marketplace, more thermometers are used without first checking the trackable accuracy or fitness of purpose, but the accuracy and suitability of your thermometer for its intended application could be the difference between passing and failing a health and safety audit, wasting a every industrial process, or being correct the first time.
When choosing a thermometer, it is important to understand its associated application, temperature measurement range, resolution, precision, and the maintenance required to achieve repeatable measurements. Some applications will require you to achieve a much more accurate reading than others. You should also consider the environment in which the thermometer is used. In a professional setting, the accuracy of your reading will ultimately affect the credibility of your future measurements and overall organization.
So let's briefly consider the types of thermometer on the market and their proven application.
Traditional Thermometers (Spirit Filled)
Often the cheapest and most popular type of thermometer, they are ideal for use at home or in non-specialized settings where traceable precision is not required. They have an indication of the spirit level, are easy to read and generally measure in both degrees C and degrees F. They can often be wall-mounted or immersed in liquids, and require very little maintenance. These thermometers have variable measurement ranges, resolutions, and body temperature instrument.
Dual Sensor / Multiple Sensor Thermometers
Often used in a professional environment, these thermometers allow simultaneous monitoring of two or more environments over short and long periods of time. They are ideal for applications such as indoor and outdoor temperature comparisons, monitoring of storage areas, and classroom maintenance. A package typically consists of a main display unit and external temperature sensors. Each reading from the external sensor is displayed on the main unit. The main unit can generally be mounted on the wall or on the desk, and traceable accuracy is recommended. These thermometers have variable measurement ranges, resolutions, and precision.
Irreversible temperature labels
The temperature indicator labels are self-adhesive, temperature-proof sheets. They are ideal for use in processes where specific temperature values must be achieved, such as sterilization. They are also suitable for use where temperature values should not be exceeded, such as motor control or bearings. They are a relatively cheap but effective way of achieving permanent precision records. Each segment of foil on a label is sensitive to a different temperature and when exposed to classification will turn black. Each segment has both ° C and ° F temperature values. Each label is oil and water resistant, and the color change is irreversible even after the measured object cools down. After use, the labels can be removed. These thermometers have variable measurement ranges, resolutions, and precision.
Fixed and wired probe thermometers
Fixed probe thermometers are designed to provide instant readings of food, liquid, and semi-solid samples through their fixed probe, which will be suitable for both immersion and penetration. They are ideal for use in the catering sector for hygiene tests, points of sale and laboratories. Being very easy to use and highly portable, probes will vary in size, material, and maneuverability. Wired probe thermometers are similar to fixed probe thermometers, the difference is that the probe is attached to the thermometer through a wire. This maximizes utility without compromising precision. Trackable accuracy is recommended if used in a professional environment. These thermometers have variable measurement ranges, resolutions, and precision.
