M Series M31 – Advanced Thermal Imaging Camera with Radiometric & Inspection Features

Introduction

The M Series M31 is a professional-grade thermal imaging camera designed for industrial inspections, predictive maintenance, and precision thermal measurements. Featuring high-resolution thermal imaging, visual integration, and advanced measurement tools, it delivers reliable results for both indoor and outdoor applications.

Main Description

The M31 comes equipped with a 384 × 288 IR sensor and SuperIR up to 768 × 576 pixels, providing highly detailed thermal images. Its NETD is <35 mK, ensuring excellent thermal sensitivity, and it operates at an image frequency of 50 Hz. The detector pitch is 17 μm, with a focal length of 15 mm and F1.0 aperture, offering a field of view of 25° × 19° and a spatial resolution of 1.13 mrad. The minimum focus distance is 0.1 m (0.33 ft), and the camera supports Laser Assisted AF, Continuous AF, AF, Manual Focus, and Touch AF with an approximate 2-second focus speed.

The 4.3” LCD touch screen (800 × 480 pixels) displays images in multiple modes: Infrared, Visual, Fusion, PIP, and Blending. A wide variety of color palettes is available, including White Hot, Black Hot, Rainbow, Ironbow, Red Hot, Fusion, Rain, and Blue Red. Color alarm settings include Above, Below, Interval, Insulation, and Condensation detection.

Temperature measurements range from -20°C to 650°C (-4°F to 1202°F) with a maximum accuracy of ±2°C / ±2%. Measurement tools include Center Spot, Hot Spot, Cold Spot, and user-definable options such as Delta T, 10 spots, 1 line, 5 rectangles, and 5 circles. The camera supports inspection route planning and Level and Span adjustment via Auto, Manual, or 1-Tap touch-screen.

Data is stored on a removable 64 GB Micro SD card, capable of storing approximately 60,000 images. Video capabilities include MP4 format and radiometric video, with streaming over UVC and Wi-Fi. Annotations can include voice notes (max 60 seconds) and text notes (max 200 characters).

The M31 integrates a visual camera (8 MP), a laser pointer (Class II, 635 nm, <1 mW), and a laser distance meter for indoor distances up to 50 m (164 ft) and outdoor distances up to 10 m (33 ft). It features LED lighting, GPS, and compass for enhanced field usability.

The camera is powered by an interchangeable and rechargeable Li-ion battery, providing approximately 4 hours of operation and 4 hours for a full charge. It has IP54 protection, withstands 2 m drop tests, and meets multiple safety, EMC, vibration, and shock standards.
