    Testo Thermal Imaging Cameras

    Thermal imaging cameras are handheld, non-contact devices that capture detailed images in low-light and hard-to-see environments. They do this by detecting infrared energy (heat) and converting it into a visual image. Thermal cameras are essential tools for troubleshooting, identifying potential hotspots, and ensuring machinery and equipment operate correctly and efficiently.

    RS offers a range of high-performance, state-of-the-art thermal imaging cameras and measurement equipment from industry-leading brands, including FLIR, Fluke, Testo, and, of course, RS PRO. RS also offers a calibration service if required.

    How Does a Thermal Imaging Camera Work?

    Thermal imaging cameras, also known as infrared or heat cameras, are point-and-shoot devices that allow users to visualise thermal energy in real time. They interpret temperature variations as different colours, with warmer areas typically appearing red and yellow, while cooler areas are shown in purple or blue. This technology, known as thermography, has numerous applications, such as detecting thermal bridges and structural defects in buildings, checking underfloor heating systems, and identifying wear in machinery before failures occur.

    Capturing thermal images begins with an external lens focusing infrared radiation onto an internal thermal sensor. This sensor, along with processing electronics, converts the captured heat energy into digital data. This data is then used to represent the temperature distribution across the scene visually. These visuals can be used for immediate on-site diagnosis or stored for later analysis using dedicated software, enabling in-depth evaluation and reporting.

    What Do Thermal Imaging Cameras Detect?

    Thermal imaging cameras detect infrared radiation, which is emitted by any object with a temperature above absolute zero (-273.15°C or 0 Kelvin). However, they are most effective in visualising objects at temperatures commonly encountered in practical applications, such as electrical components, machinery, and building structures. This allows these cameras to visualise a wide range of objects and scenarios, including:

    • People and animals
    • Electrical components and overheating circuits
    • Mechanical equipment with wear or potential failures
    • Building structures with insulation deficiencies or moisture
    • Plumbing systems with leaks or blockages
    • Vehicles with engine, brake, or exhaust issues
    • Fire hazards and hot spots

    This ability to "see" heat makes thermal imaging cameras valuable tools across various industries for identifying problems that are invisible to the naked eye.
