  • Brand: Zunate
  • Model Name: Zunatek3614tfexz7410
  • Product Type: Infrared Thermal Imager
  • Key Features: Portable, built-in memory, long battery life

Technical Background

Thermal imaging technology utilizes the principle of infrared radiation to capture the thermal energy distribution of objects and convert it into visual images. Thermal imagers are equipped with infrared sensors that detect the infrared radiation emitted from different temperature zones, which is then processed through specific algorithms to generate thermal images. This technology finds wide applications in industries, construction, medicine, etc., for tasks such as detecting equipment malfunctions, thermal losses in buildings, medical diagnosis, and more. Different models of thermal imagers have varying resolutions, temperature ranges, and sensitivities, thus possessing distinct advantages and limitations in different application scenarios.

Design and Build Quality

The Zunatek3614tfexz7410 features an ergonomic handheld design with a smooth aluminum alloy exterior. It feels sturdy and durable in hand. The 2.4 inch display is sufficiently large and clear for previewing images and thermal data. Buttons are logically laid out for easy operation. The imager is also lightweight and compact for portability.

Image Quality and Performance

This thermal camera uses a 24x32 MLX90640 thermal sensor and produces images with a resolution of 240x320 pixels. While image quality is relatively low compared to higher-end models, the Zunatek3614tfexz7410 is able to effectively highlight temperature variations and anomalies. Accuracy is rated at ±2°C for the central area from 0-100°C. The 75°x110° field of view allows for inspection of large areas.

The 8Hz refresh rate provides smooth real-time thermal imaging. The imager can detect temperatures ranging from -40°C to 300°C, covering needs for most residential and commercial inspection applications. Users can adjust the emissivity from 0.1 to 0.99 for more accurate temperature measurements.
