M Series M31 – High-Performance Handheld Thermal Camera for Industrial Applications
Introduction
The M Series M31 is a robust handheld thermal camera designed for professional industrial, electrical, and building inspections. It provides precise temperature detection and imaging, allowing engineers and technical professionals to identify potential hazards, system inefficiencies, or maintenance needs with confidence.
Main Description
Equipped with a 384 × 288 IR resolution and SuperIR 768 × 576, the M31 delivers high-clarity thermal imaging with a NETD < 30 mK for exceptional sensitivity. Its 6.4 mm F1.0 lens offers a 41.1° × 30.5° field of view and a spatial resolution of 1.87 mrad, allowing accurate detection of small temperature differences from close range. Manual focus ensures precise image targeting for detailed inspections.
The camera’s 8 MP visual camera supports multiple modes, including fusion, PIP, and blending, enabling simultaneous thermal and visible analysis. Its 3.5" LCD touchscreen offers intuitive operation with digital zoom from 1.0x to 8.0x and multiple color palettes for versatile inspection scenarios.
Advanced measurement features include center, hot, and cold spot detection, along with 10 user-definable points, lines, rectangles, and circles. Storage via 64 GB Micro SD card allows approximately 100,000 images and 300 hours of video, with support for both voice and text annotations.
Connectivity options include Wi-Fi (2.4/5 GHz), Bluetooth 4.2, and USB Type-C. The M31 is powered by an interchangeable Li-ion battery with ≈4 hours of operation. Its rugged IP54-rated protection and 2 m drop resistance make it suitable for challenging field environments.
