Infrared Thermometers

An infrared (IR) thermometer measures temperature by detecting the thermal radiation that an object emits. This allows for temperature assessments from a distance, eliminating the need for direct contact with the surface. Such a feature is particularly beneficial for gauging temperatures in hard-to-reach areas and for obtaining accurate readings of moving components or objects in controlled environments.

RS Australia offers a wide range of high-quality infrared thermometers (also referred to as laser thermometers or laser temperature guns) from leading brands such as Fluke and Testo. Buy from RS today to experience the convenience and versatility of our industrial products and solutions.

How Does an Infrared Thermometer Work?

Infrared thermometers operate on the principle of thermal radiation. Every object emits infrared radiation, and the amount of radiation emitted is directly related to its temperature. The infrared thermometer has a lens which captures this radiation and converts it into an electrical signal, which is then displayed as a temperature reading on the device.

However, as all objects emit infrared radiation, it is possible for nearby objects emitting their own thermal radiation to interfere with the measurement – such as the thermal body temperature emitted by the user or the ambient temperature of the surroundings.

As such, most non-contact thermometers can be calibrated to mitigate interference and customise the device to the application at hand. With adjustable temperature ranges and distance-to-spot ratios, an IR thermometer is a versatile and easy-to-use temperature measurement solution. Handheld infrared thermometers also have a laser for aiming purposes, so you can be sure your contactless measurement remains accurate.

Infrared Laser Thermometer Types

Digital Infrared Thermometers

Digital infrared thermometers provide a clear and easy-to-read temperature display on an LCD screen. They are versatile and suitable for various applications across multiple industries.

Industrial Infrared Thermometers

Industrial infrared thermometers are designed for demanding environments. They often feature rugged construction, wider temperature ranges, and advanced features like data logging and alarms.

Handheld Infrared Thermometers

Handheld infrared thermometers are portable and easy to use, making them suitable for both professional and home use. They are commonly used for spot-checking temperatures in various settings.

What Type of IR Thermometer Do I Need?

Non-contact infrared thermometers are known for their durability and versatility. They typically feature LCD screens that can display either easily discernible numerical values, or more advanced real time heat map overlays. With various models offering different accuracy levels and maximum temperature ranges, it’s simple to choose an infrared thermometer that fits your specific needs and budget.

• Pocket-size models provide added convenience, while ATEX-certified versions are designed for hazardous environments..
• Temperature guns often feature additional functionalities such as laser aiming, adjustable emissivity settings, and data logging capabilities.
• Thermometer lasers combine the precision of laser aiming with infrared temperature measurement. They are particularly useful for long-range measurements or situations where direct contact is not possible.

Infrared thermometers, temperature guns, and thermometer lasers offer exceptional versatility and efficiency for non-contact temperature measurement. Their non-invasive design, rapid response time, and broad temperature range make it easy to find a model that meets your requirements and budget.

How to Calibrate an Infrared Thermometer

Calibration ensures the accuracy of your infrared thermometer. Here are the general steps:

1. Prepare a Reference Source: Use a calibrated reference thermometer or a blackbody source with a known temperature.
2. Adjust Emissivity: Set the emissivity of the infrared thermometer to match the emissivity of the reference source.
3. Take Measurements: Take temperature readings of the reference source with both the infrared thermometer and the reference thermometer.
4. Compare Readings: Compare the readings from both thermometers. If there is a significant difference, adjust the infrared thermometer's calibration settings according to the manufacturer's instructions.
5. Repeat: Repeat the process until the infrared thermometer's readings match the reference source's temperature.

Industrial Applications of Infrared Temperature Guns

Manufacturing and Industrial Processes

Industrial infrared thermometers are essential for monitoring temperatures in manufacturing processes, ensuring product quality and safety.

HVAC and Building Maintenance

Infrared thermometers are used to identify hot spots, leaks, and insulation problems in HVAC systems and building structures.

Automotive and Transportation

Handheld infrared thermometers are used for troubleshooting engine problems, checking tire temperatures, and inspecting brake systems.

Food Safety and Hygiene

Non-contact infrared thermometers are used in the food industry to monitor food temperatures during storage, preparation, and serving, ensuring food safety and compliance with regulations.

Electrical and Electronics

Infrared thermometers are used to detect overheating components in electrical panels, circuit boards, and electronic devices.

How to Select the Right Infrared Thermometer

Temperature Range

The temperature range of the infrared thermometer should cover the temperatures you need to measure. Consider the minimum and maximum temperatures you'll be working with.

Accuracy

The accuracy of the infrared thermometer is crucial for reliable measurements. Choose a thermometer with an accuracy level that meets your application's requirements.

Distance-to-Spot Ratio

The distance-to-spot ratio determines the size of the area measured by the thermometer at a given distance. Choose a thermometer with an appropriate ratio for your target size and measurement distance.

Emissivity

Different materials have different emissivities, which affect how much infrared radiation they emit. Ensure the infrared thermometer you choose has adjustable emissivity settings to accommodate various materials.
