Digital Infrared Thermal Imaging Camera 32x24

Compact Infrared Thermal Imaging for Quick Checks

This digital infrared thermal imaging camera is designed for simple, close‑range temperature observation in a wide variety of everyday technical and maintenance scenarios. Using an MLX90640 infrared sensor array, it converts heat signatures into a clear, color thermal image so you can visually compare hot and cold areas on equipment, walls, or components within approximately 1 meter.

The device measures surface temperatures from approximately -40°C to 300°C and displays results on a 1.8 inch TFT screen (160×128 resolution). The thermal sensor array provides a 32×24 pixel thermal image (768 sensing points) with a 55° × 35° field of view, allowing you to see relative temperature distribution rather than fine structural detail. It displays center point, maximum, and minimum temperature readings on screen for quick reference. Typical measurement accuracy in the central area from 0-100°C is ±2°C, making it suitable for basic diagnostic checks where approximate values and relative differences are sufficient.

The camera includes a built‑in rechargeable battery and USB Type‑C port (5V/1A) for charging and data connection. With 4 MB of internal memory, it can store around 90 thermal images that can be copied to a computer via USB. Photos are captured with a single button press; navigation keys allow you to review and exit image playback. The low 8 Hz refresh rate is intended for static or slow‑changing scenes, rather than fast‑moving targets. Because the sensor detects many small temperature variations, the display will naturally show multiple colors and slight fluctuations even on a uniform surface-this indicates normal, sensitive operation, not a fault.

Why It's a Smart Choice

• Visualizes heat distribution quickly at close range for basic inspections and comparisons.
• Simple controls, onboard storage, and USB Type‑C connectivity streamline capturing and transferring images.
• Wide temperature range and compact size make it practical for workshop, lab, and general maintenance use where approximate readings are sufficient.

FAQ

Q: What is the effective use distance for this thermal camera?
A: It is best used within about 1 meter of the target for clearer thermal patterns and more reliable temperature readings.

Q: Can it be used for high‑precision diagnostics or detailed leak detection?
A: No. The 32×24 thermal resolution and ±2°C accuracy are intended for simple temperature checks and relative comparisons, not for tasks that require high spatial detail or tight tolerances, such as floor heating layout mapping, wall leak tracing, or smartphone repair diagnostics.

Q: Can it replace a standard digital camera or night‑vision device?
A: No. It is a thermal imager for observing heat patterns, not a conventional camera. It is not suitable for photographing small animals at night or for general photography.

Q: Can it detect hidden cameras or very small electronic hotspots?
A: It is not designed for security sweeps or pinpointing small components on dense circuit boards. The low resolution and refresh rate make it better suited to larger, simple targets and general temperature contrast checks.

Q: Why does the image show many colors and fluctuating readings on a plain surface?
A: The sensor measures 768 individual points, each with slightly different temperatures. Small variations are normal, so the display will show multiple colors and minor temperature changes over time. This behavior indicates that the sensor is sensitive to subtle temperature differences.
