Which Thermometer Is Best Suited For Your Needs? An Overview

Many people associate thermometers with needing to check for a fever when they are sick. However their application in certain industries has made workflows smoother, quicker, and more efficient. The heating, ventilation and air conditioning (HVAC) sector relies heavily on temperature management to maintain quality control and ensure health and safety best practices are followed. The pharmaceutical industry offers another fine example, as medicines often need to be maintained at a certain temperature. But what is the difference between an infrared thermometer and a surface thermometer? Is there one? Read on to find out more!

#1 – The Surface Thermometer

Surface thermometers offer a broad range of uses, such as within the engineering sector, the sanitation sector, or the HVAC sector. They are designed to accurately measure the temperature of any given surface they attach to, with results in seconds. Some thermometers will have functionalities which will allow you to measure different sites at once using different probes – a big plus in large industrial environments.

Commonly used for: Temperature measurement of heating management systems, refrigeration systems, ovens and hobs.

Not a good fit for: Conveyor belt processes, surface areas which are out of reach or cannot be contaminated by contact.

#2 – The Infrared Thermometer

Although infrared thermometers also measure surface temperature, they are an excellent choice for any industry that needs quick and accurate temperature readings from a distance. Their application is particularly handy for measuring high temperatures, measuring temperatures at a distance, or measuring the temperature of moving objects. They provide readings instantaneously. Keeping their sensors clean and free of dirt is important to obtain the most accurate readings. It is important to note that infrared thermometers only measure surface temperatures, and not internal temperatures.

Commonly used for: Measuring the temperature of moving, out of reach or easily contaminated items. The HVAC and Manufacturing industries in particular make great use of these.

Not a good fit for: Measuring core temperatures

#3 – The Immersion Thermometer

Immersion thermometers – sometimes also called penetration thermometers – are ideal for measuring the temperature of liquids and pastes. They can be used for anything from checking heating systems to testing if a loaf a bread is cooked through. However, they are not as effective at measuring temperature of large surface areas. Their long probes also mean that they can also be used for checking the temperature of frozen foods. A good thermometer will be HACCP compliant, like the Testo 106 Penetration Thermometer.

Commonly used for: Fast measurement of core temperature, such as in food control.

Not a good fit for: Easily contaminated items, such as bio-pharmaceuticals
