M Series M20W – High-Resolution Handheld Thermal Camera for Industrial Inspections
Introduction
The M Series M20W is a professional-grade handheld thermal imaging camera designed for precise temperature measurement and reliable diagnostics in industrial, electrical, and building maintenance applications. Its advanced SuperIR technology and wide field of view deliver crisp thermal details, making it ideal for engineers, maintenance professionals, and inspection experts who require fast, accurate thermal analysis in demanding environments.
Main Description
The M20W features a 256 × 192 infrared detector enhanced with SuperIR technology, achieving a detailed 512 × 384 thermal resolution for superior image clarity. With a NETD below 40 mK, the device detects even the smallest temperature differences, ensuring accurate diagnostics in critical operations. The 3.6 mm F1.0 lens provides a 50° × 37.2° field of view, enabling users to capture more in each frame — perfect for large surface scans and confined spaces alike.
Equipped with a 3.5" LCD touchscreen (640 × 480), the M20W offers intuitive operation, manual brightness control, and a wide selection of color palettes for clear visual interpretation. The built-in 8 MP visual camera allows fusion and PIP modes, combining thermal and visible imagery for context-rich reporting.
Measurement versatility is supported through multiple tools, including center spot, hot/cold spot, and up to 10 user-defined measurement points. Professionals can save and annotate findings using voice or text notes, while data is stored on a removable 16 GB Micro SD card for easy access.
For connectivity, the M20W supports Wi-Fi (2.4/5 GHz) and Bluetooth 4.2, along with USB Type-C for fast data transfer. Its interchangeable Li-ion battery offers up to 6 hours of continuous use, and the rugged IP54-rated housing with 2-meter drop resistance ensures reliability in tough field environments.
