Infrared thermometers are a game-changer for industries where temperature monitoring is key. (That’s a pretty broad range of industries, from food service to healthcare and manufacturing.) These non-contact temperature measurement devices, also known as non contact thermometers, temperature guns, infrareds, or infrared pyrometers, use infrared radiation to gauge the surface temperature of objects or environments. That means you can measure temperatures without having to touch the object—you know, for those applications where hygiene and safety are paramount.
That’s where the IR thermometer comes in. It’s a compact, handheld, portable device that lets you take temperature readings from a distance. (No more worrying about contamination or damage to the object.) A built-in laser pointer helps you target the area you want to measure, often by pointing to a single point. Some models use a single laser, which indicates the center of the measurement area, but may not represent the entire spot being measured, while dual laser models can outline the actual zone for greater determinations. And with some models, you can even store temperature readings for later review.
But what exactly is an IR thermometer? Simply put, it’s a sophisticated tool that uses infrared radiation to measure surface temperatures. The device measures the energy emitted by an object as infrared radiation, and this energy is focused by a lens onto sensors that convert it into an electrical signal, which is then used to produce a temperature reading. Focusing the lens is essential to concentrate the infrared energy onto the sensor for accurate readings. That means you can rely across a wide range of industries. Whether you’re ensuring food safety, monitoring patient health or maintaining industrial equipment, an IR thermometer provides a reliable solution.
When choosing the right infrared device for your needs, consider the temperature range you need to measure. You’ll want to make sure the thermometer you choose covers that range. Accuracy and repeatability are also crucial. Look for a model that provides an accuracy of ±1.5°C or ±2.7°F. And don’t forget about the distance to spot ratio—the size of the area being measured. A higher ratio means a smaller measurement area.
Infrared devices come in a range of types and feature sets. You can choose from handheld models, fixed-mount models, IR thermometer guns, dual models, and infrared pyrometers. Some models come with additional features such as alarms, data storage and a carrying case with a tool bucket organizer bag.
Using an infrared is relatively straightforward. Just make sure to hold it at the correct distance from the object being measured. That’s specified in the user manual. With the right thermometer by your side, you can take accurate temperature readings with ease. The thermometer produces a temperature reading by focusing infrared energy onto its sensors, and the measurement is determined by the amount of energy emitted from the object. The device reads the surface temperature, and the actual temperature may differ due to factors like emissivity and surface properties.
Using an thermometer effectively starts with aiming the thermometer at the center of the object you’re measuring. If you have a laser pointer, align it with the object to target that exact spot or point. This helps ensure you’re getting a precision, especially when focusing on a single point for spot checks.
Taking multiple readings is also key to getting accurate handling. That way, you can average out any anomalies and get a consistent temperature reading. (And yes, that does mean you should take multiple readings.)
When you’re taking those findings, consider the environment you’re in. Humidity and altitude can affect your readings, and ambient temperatures—especially near room temperature—can also influence results. Make sure you’re within the specified operating conditions for your thermometer.
IR thermometers are used in many industries and applications. Food service, for example, relies on them to ensure food is cooked to a safe internal temperature. That’s a fast and hygienic way to check—no direct contact required. In healthcare, they help measure body temperature without physical contact, reducing the risk of cross-contamination.
Industrial applications rely on precise temperature measurement for process control and quality assurance. Scientific research uses thermometers to measure temperature accurately and quickly in climate studies, materials science and other areas. In industrial settings, infrared thermometers are often used to measure the temperature of objects moving on a conveyor belt or in a controlled atmosphere, where contact sensors or probe type may not be practical.
To get accurate and reliable temperature readings from your thermometer, follow these safety precautions and maintenance guidelines. That means using it within the recommended temperature range (usually -20°C to 50°C or -4°F to 122°F) for optimal performance. You should also use it in environments with relative humidity of 80% or less to prevent damage and get accurate readings.
Store your thermometer at sea level or below to avoid damage from altitude changes. Handle it with care to prevent damage from drops or impacts. Calibrate it regularly to maintain temperature accuracy. And clean it regularly to prevent contamination and get accurate readings.
When it comes to medical and food applications, IR thermometers must meet stringent regulatory requirements to ensure reliability and safety. That’s where certifications like FDA clearance and NIST certification come in. Some thermometers may also carry CE, UL and other certifications, depending on their intended use and regional regulations.
Infrared thermometers are generally reliable, but issues can arise. Regular calibration is essential to ensure accuracy. Readings can be adjusted, and devices are tested to ensure they produce accurate data. Check your user manual for calibration instructions or contact the manufacturer for guidance. Calibration ensures the thermometer maintains its accuracy over time.
To ensure accurate readings with your infrared temperature gauge, use the correct emissivity setting for the object you’re measuring. Different materials emit infrared radiation differently, so get that setting right. Avoid reflections from surrounding objects, which can affect the accuracy of your readings. Highly reflective surfaces, such as polished metals, can interfere with readings, so applying masking tape or tape to the surface can help improve measurement accuracy by providing a consistent emissivity reference. Use a thermometer with a high distance to spot ratio to ensure accurate measurements. And take readings at the correct angle, as specified in the user manual.
The field of infrared temperature gauge technology is continually evolving. Future developments may include improved accuracy and resolution, increased temperature ranges and faster response times, and advanced features like high and low alarms, dual laser pointers and rapid detection capabilities.
Infrared thermometers are becoming more user-friendly to handle and transport. That’s thanks to more ergonomic designs—and lighter form factors that make them easier to move around.
Those advancements are also making infrared thermometers more compatible with other technologies. Wireless connectivity and data logging capabilities make data management seamless.
That means infrared thermometers meet the highest standards for accuracy and safety. We’re seeing a big push to ensure that’s the case—regulatory compliance and certification are top priorities.
All these advancements are broadening the scope of infrared thermometers. They’re becoming even more valuable in industrial, medical, foodservice and agricultural applications. Where technology goes, infrared thermometers will be right behind, helping to maintain safety, quality and efficiency across the board.
It’s important to note that infrared thermometers cannot read through glass and only measure surface temperatures. When comparing to other devices, such as thermocouples, contact sensors, probe type sensors, and other probe type sensors, infrared thermometers and non contact thermometers offer advantages in situations where direct contact is impractical, such as moving objects, hazardous environments, or when rapid, hygienic, or remote measurements are needed.
Temperature measurement plays a vital role in countless industries, from ensuring food safety in kitchens to monitoring patient health in hospitals, measuring soil temperature for optimal plant growth, and maintaining equipment in manufacturing plants. Infrared thermometers have revolutionized the way we approach measuring temperature, offering a non-contact solution that is both safe and efficient.
