3. Product Features

• Dual Light Fusion Imaging: Equipped with a 2MP visible light camera and an infrared camera, the GH192 offers a 2.8" 240x320 IPS display and a 25Hz frame refresh rate. This enables faster response and more detailed inspections by outlining target objects upon activation. Note: Enable "File Transfer" in settings before exporting images.
• Auto Temperature Tracking + Temperature Alarm: The imager automatically captures center point temperature and locks onto high/low temperatures within a range of -4°F to 1022°F. It features 3-point heat tracking (target temp, minimum temp, maximum temp). High-temperature and low-temperature alarms provide clear alerts on the screen for temperature abnormalities.
• 3 Image Modes And 6 Color Palettes: Choose from Fusion, Thermal, and Conventional Light modes. Six adjustable color palettes are available: White Hot, Black Hot, Iron Red, Rainbow, Red Hot, and Fusion, allowing selection based on specific work needs.
• Durable & Portable Design: Offers up to 8 hours of runtime and USB-C charging. It is 6.6ft drop-resistant and IP54 rated, ensuring durability for tough use.
• Professional-Grade Accuracy: Provides a precision of ±2°C. Emissivity can be adjusted based on materials (e.g., wood, bricks) and object distance can be modified for accurate temperature readings across various surfaces. Suitable for home inspections, facility maintenance, HVAC troubleshooting, and electrical/mechanical system checks.

5.3 Adjusting Emissivity and Distance

For accurate temperature readings, adjust the emissivity setting based on the material being inspected. Navigate to "Settings" > "Emissivity" and select from predefined materials (e.g., Human Skin, Printed Circuit Board, Cement Concrete, Ceramic, Rubber, Paint, Wood, Asphalt, Brick, Sand, Soil, Cotton, Cardboard, White Paper, Water) or set a custom value. Adjust the object distance in "Settings" > "Distance" for optimal focus and accuracy.

5.4 Temperature Alarms

Enable and configure high/low temperature alarms in "Settings" > "Temperature Alarms". When a target's temperature exceeds or falls below the set thresholds, a visual alert will appear on the screen.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device body. For the lens, use a lens cleaning cloth and solution. Do not use abrasive cleaners.
• Storage: Store the camera in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: For long-term storage, ensure the battery is charged to approximately 50%. Recharge periodically to maintain battery health.

7. Troubleshooting

• Device not powering on: Ensure the battery is sufficiently charged. Connect to a power source using the USB-C cable.
• Inaccurate temperature readings:
  • Check and adjust the emissivity setting for the material being inspected.
  • Verify the object distance setting is appropriate.
  • Ensure the lens is clean and free from obstructions.
• Cannot transfer files to PC:
  • Ensure "File Transfer" is enabled in "Settings" > "More Settings".
  • Use the provided USB-C cable and ensure it's securely connected.
  • Try a different USB port on your computer.
• Screen is too dim/bright: Adjust brightness in "Settings" > "More Settings" > "Brightness".
