M31T
The HIKMICRO M31T is the specialized telephoto variant of the professional M-Series. While it shares the flagship 384 × 288 resolution and manual focus accuracy of the M31, the "T" model is factory-equipped with a narrow 12° telephoto lens. This configuration is specifically engineered for thermographers who need to maintain a safe distance from high-voltage assets, hazardous machinery, or distant infrastructure without sacrificing thermal detail or measurement accuracy.
Key Professional Advantages
Specialized 12° Telephoto Optics: The narrow Field of View (FOV) provides significantly higher spatial resolution (IFOV of 0.55 mrad) compared to standard lenses. This allows you to "zoom in" on small components—like a single bolt on a high-voltage transmission tower—from a much safer standing position.
Surgical Manual Focus: Precision is non-negotiable at a distance. The M31T’s manual focus ring gives you total control to sharpen the thermal image of distant targets, ensuring that the temperature data you collect is focused on the component, not the background.
Flagship Image Clarity (SuperIR): Using HIKMICRO’s SuperIR technology, the native 384 × 288 sensor is upscaled in real-time to 768 × 576 (442,368 pixels). This provides sharp, high-definition thermal maps that reveal critical heat signatures on distant or microscopic targets.
High-Speed 25 Hz Performance: The fluid refresh rate ensures that you don't lose your target while scanning distant lines or moving equipment. The real-time response is essential for identifying intermittent thermal anomalies in active industrial environments.
Advanced On-Device Analysis: Utilize the 3.5” touchscreen to set multiple measurement points and use the "Level & Span" feature to instantly isolate thermal variances in complex, low-contrast scenes.

Ideal Telephoto Applications
Electrical Utilities: Safely inspecting high-voltage insulators, connectors, and pylons from ground level.
Substation Maintenance: Identifying hot spots on distant transformer bushings and high-racks without the need for lift equipment.
Large-Scale Facilities: Monitoring rotating machinery or steam valves that are located behind safety barriers or in hard-to-reach ceiling heights.
Infrastructure Audits: Detecting thermal anomalies in bridges, chimneys, or large-scale HVAC units from a distance.
