Introduction to the M305 Professional Handheld Infrared Thermal Imager in the Image**  

1. Product Appearance and Design**  
- **Overall Design**: Compact ergonomic structure with a streamlined grip for comfortable, extended operation.  
- **Color Scheme**: Dominant black (professional and robust) with red accents on the handle and screen edges (enhanced visibility).  
- **Display**: Front-facing pseudo-color thermal imaging screen, where yellow/orange indicates high-temperature zones, and blue/purple represents cooler areas.  
2. Core Features and Functions**  
- **Hardware Specifications**:  
  - **5MP Visible Light Camera**: Captures high-resolution visible light images.  
  - **Infrared Detector**: 12μm uncooled microbolometer with 384×288 resolution.  
  - **Thermal Sensitivity**: 35mK (high-precision temperature detection).  
  - **Manual Focus**: Adjustable focus for sharp thermal imaging.  
- **Key Functions**:  
  - **Non-Contact Temperature Measurement**: Range from -20°C to +1500°C (varies by model).  
  - **Thermal Imaging Visualization**: Real-time temperature distribution display for identifying hotspots or cold spots.  
  - **Data Recording**: Supports image/video storage for post-analysis.  
3. Working Principle**  
1. **Infrared Detection**: Captures surface radiation in the 8–14μm wavelength range via the infrared detector.  
2. **Signal Processing**: Converts infrared signals into electrical signals, generating a temperature distribution map through algorithms.  
3. **Image Display**: Visualizes thermal data in pseudo-color (e.g., red/yellow for heat, blue/purple for cold).  

4. Product Dimensions and Packaging**  
- **Size and Weight**: 670 grams net weight, dimensions: 256.4mm (L) × 105.3mm (W) × 105.1mm (H).  
- **Packaging Contents**:  
  - Main unit (thermal imager)  
  - Accessory box (battery, charger, data cable, etc.)  
  - User manual, warranty card, and factory inspection report (all in English).  

5. Design Style and Atmosphere**  
- **Tech-Savvy and Professional**: Blue-white theme evokes a calm, rational vibe, with clear layouts and organized information hierarchy.  
- **Visual Presentation**: Soft lighting and minimalist background highlight product details, combining text and visuals for quick comprehension.  

This thermal imager is ideal for power grid inspections, building diagnostics, emergency rescue operations, and more. Its portability and precision make it a reliable tool for non-contact temperature measurement across diverse scenarios.
