The FOTRIC 138S is a fixed-mount infrared camera designed for industrial temperature monitoring, predictive maintenance, and research applications. It features a 640×480 infrared resolution and a thermal sensitivity of less than 30 millikelvins (mK) at 30°C, allowing for highly detailed thermal imaging and precise detection of temperature variations. Operating within an 8–14μm spectral range, the camera supports multiple lens options, including 25°×19° (standard), 50°×38° (wide-angle), and 21°×16° (telephoto), ensuring flexibility for various monitoring needs. The FOTRIC 138S is focus-free, enabling continuous operation without manual adjustments. It supports a complete temperature range of -20°C to 650°C (-4°F to 1022°F) with an accuracy of ±2°C or ±2%, making it suitable for demanding industrial environments. The camera includes advanced measurement tools such as 5 points, 10 lines, and 10 regions, with Modbus output support, facilitating seamless integration into automated industrial systems. It features H.264 radiometric video streaming for real-time temperature monitoring and supports multiple network protocols, including IPv4, UDP, TCP, and RTSP, ensuring reliable connectivity. Designed for industrial durability, it operates in temperatures from -20°C to 65°C (-4°F to 149°F) and is housed in an IP66-rated aluminum alloy casing, providing robust protection in harsh environments. The FOTRIC 138S is an optimal choice for professionals requiring high-resolution thermal imaging for industrial automation and research applications.
