HT-19 Thermal Imaging Camera Instruction Manual
1. Overview
This product is an infrared camera that integrates surface temperature measurement and real-time thermal imaging. Unlike traditional thermometers that require individual component measurement, this infrared imaging camera saves time. Potential problems are clearly displayed on the color display screen. The central point measurement cursor aids in quick and accurate location for temperature measurement of target objects.
A visible light camera is included for enhanced differentiation. Thermal and visible images are stored on the device and can be read via USB or transferred to a computer for reporting or printing.
The product is suitable for fields such as medical treatment, fire fighting, archaeology, traffic, agriculture, geology, energy, smelting, and electronic manufacturing. It is an ideal selection for electricians, maintenance personnel, and technicians to quickly identify problem areas.
The following major functions increase the product's accuracy and usability:
- The radiation coefficient can be adjusted to increase measurement accuracy for objects with half-reflection surfaces.
- The highest and lowest temperature cursors guide users to areas with the highest and lowest temperatures in thermal images.
- Selectable color palettes are available.
2. Considerations and Safety Maintenance
Please read the instructions carefully to ensure correct measurement results:
- Do not use the device in explosive, flammable, or corrosive environments.
- The product is a precision electronic and sensitive optical device. Do not impact or drop it to avoid damage.
- Do not dismantle or remodel the product.
- A light clicking sound may occur every several seconds during operation; this is a normal phenomenon as the lens captures images.
- Clean the device enclosure with a damp cloth or weak soap. Do not use abradants, isopropanol, or solvents. Use a special optical lens cleaner for the screen.
3. Read Images
Connect the device to your computer using a USB cable to read or save images. Supported systems include Windows XP, 7, 8, 10, and Apple OS. It is recommended to use the supplied USB cable or a higher quality USB cable.
Note: When disconnecting from the computer, select "Safe Eject Device" before unplugging the cable.
To avoid file storage errors, if you encounter problems with storing files, check and fix your computer's hard disk.

The color palette menu allows changing the false color of the infrared thermal image. The product offers five color palettes: rainbow, iron oxide red, cold color, white heat, and black heat.
Suitable selection of color palettes displays target objective details better. Rainbow, iron oxide red, and cold color palettes focus on color display and are suitable for high heat contrast, improving color contrast between high and low temperatures. The black & white and white & black palettes provide a linear color representation.
The following images show the same object with different color palettes applied.
Image Examples:
- Rainbow: Shows a thermal image with a rainbow color scheme.
- Iron oxide red: Shows a thermal image with an iron oxide red color scheme.
- Cold color: Shows a thermal image with a cold color scheme.
- White heat: Shows a thermal image with a white heat color scheme.
- Black heat: Shows a thermal image with a black heat color scheme.

Press the Left key (◀) to return to the previous menu. Press "MENU" key to exit from the menu.
10. Introduction to "emissivity" sub-menu
10.1 Emissivity Description
The emissivity of the product can be adjusted from 0.01 to 1.00, with a default value of 0.95. Many common objects and materials (such as timber, water, skin, and textile fabric) effectively reflect heat energy, allowing for relatively correct measurement values. The emissivity is typically set to 0.95 for coarse objects that readily release energy. For semi-matte objects that release less energy, emissivity is usually around 0.85. Semi-glossy objects have an emissivity of approximately 0.6. Shiny objects, which are materials with low radiation coefficients, typically have an emissivity set to 0.3 during measurement.
Correctly setting the emissivity value is crucial for obtaining the most accurate temperature measurements, as surface emissivity significantly impacts the measured surface temperature.
10.2. Emissivity setting
The product provides four types of object measurement modes:
- Coarse object (e=0.95)
- Semi-matte object (e=0.85)
- Semi-shiny object (e=0.60)
- Shiny object (e=0.30)
Users can set the emissivity value using the "self-define" option based on the characteristics of the measured objects (refer to the table of "emissivity of common materials").
Operating Steps:
As shown in the figure, press the "MENU" key to enter the main menu and select the "emissivity" option. Press the Up key (▲) to enter the emissivity list.
Use the Up (▲) and Down (▼) keys for navigation to select the desired emissivity. Then press the "SELECT" key to confirm the selection. Press the Left key (◀) again to return.
If "self-defined" emissivity is selected, press the "SELECT" key to enter the edit state. Press the Left (◀) and Right (▶) keys to select the number to be changed. After the change is completed, press "ENTER" to confirm. Then press the Up (▲) and Down (▼) keys to change the value. Press "MENU" key to exit from the menu.
