Thermometers – Different Types And Use

Thanks to the advancements in technology, today you can find a variety of thermometers designed to accomplish different functions. Hence, it is essential that you understand the range of products available and their purposes.

Electronic Probe Thermometer

Apart from choosing the right device it is also important that you consider when you need traceable accuracy, which is the difference between reliable readings and fake readings. When a reading is not accurate, it can compromise the safety and health of people or lead the waste of an entire industrial process. Make sure to choose right and get familiar with calibration.

Here are the most common types of thermometers and their use:

Analogue Thermometer

Analogue thermometer is the most popular and most affordable type of thermometer. It is perfect for home applications or in non-specialists environments where traceable accuracy is not needed.

Analogue thermometer features simple display that is easy to read and typically measure in whether °C or °F. Most devices are wall mountable, require low maintenance, can be immersed in liquids and provide variable measurement range, accuracy and resolution.

Electronic Probe Thermometer

Electronic probe thermometer is a device designed to provide instant temperature readings of liquids, food and semi-solid samples. The electric thermometer probe is commonly equipped with a pointed tip, which makes it ideal for immersion and penetration. Electronic probe thermometer is the perfect thermometer for use in retail outlets, laboratories and catering trade for hygiene testing. Typically, there are two types of this thermometer available:

  • Fixed electric thermometer probe: This type of thermometer feature a pen link structure and is usually less expensive and easy to use.
  • Wired electric thermometer probe: This type of thermometer if usually more complex with extra features and at least 1 meter cable.

Electronic probe thermometer can come with a variety of features such as folding designs, alarms, etc. Because this thermometer is designed for more professional environments, traceable calibration is something you should definitely look for.

Overall, electronic probe thermometer is pretty easy to use with simple displays and is highly portable. It can vary in material, size and maneuverability and can provide variable measurement range, accuracy and resolution. Note that wired probes increases versatility without compromising accuracy.

Infrared Thermometer

Infrared thermometer is a non-contact measurement device. Its non-contact feature makes it the best tool for measuring high and low surface temperatures. This thermometer usually includes a laser targeting system designed to show the middle of the measurement area. From all the thermometers, this type can be the most complex to use due to emissivity and spot-size. Infrared thermometer is usually used in food preparation surfaces as well as in air conditioning systems and automotive trade.

The non-contact feature of this device allows extreme temperatures to be safely taken. Moreover, you can take a measurement at the pull of a trigger and obtain a variable measurement range, resolution and accuracy. Laser targeting systems allow accurate sensor placement.
