The HT-D9 Thermal Imaging Monocular is a high-resolution handheld thermal viewer designed for wildlife observation, farm monitoring, property inspection, electrical inspection, machinery maintenance, building inspection, search support and general thermal observation.

At the core of the HT-D9 is a 640 × 512 uncooled infrared detector with a 12 μm pixel pitch, providing detailed thermal imaging for detecting and observing heat signatures in darkness and visually challenging environments. The system operates at approximately 25 Hz and features NETD ≤60 mK thermal sensitivity.

A 3.5-inch colour TFT display with 640 × 480 resolution provides a clear viewing interface, while five thermal colour palettes allow users to select the most suitable presentation for different thermal scenes. Integrated multi-scale image enhancement and automatic shutter correction further support clear and consistent thermal imaging.

The HT-D9 also includes thermal image capture, JPG photo format, 8GB built-in storage and a rechargeable 26650 lithium battery, providing a self-contained portable thermal observation system.

640 × 512 Thermal Imaging

The HT-D9 features a 640 × 512 thermal detector with 12 μm pixel pitch, providing substantially detailed thermal imaging for outdoor and inspection applications.

The high-resolution thermal sensor supports:

• Detailed heat-source observation
• Clear separation between nearby thermal objects
• Better image quality during digital enlargement
• Improved viewing of smaller heat sources
• Detailed observation of complex thermal environments

This makes the HT-D9 suitable for users who require greater thermal detail than lower-resolution handheld thermal viewers.

NETD ≤60 mK Thermal Sensitivity

The HT-D9 detector provides a thermal sensitivity rating of NETD ≤60 mK.

Thermal sensitivity determines the device's ability to distinguish small temperature differences between objects and their surroundings, supporting effective heat-source observation across varied environments.

Approximately 25 Hz Refresh Rate

The HT-D9 operates at approximately 25 Hz, providing smooth image presentation during handheld scanning and observation.

The refresh rate supports:

• Handheld thermal scanning
• Walking observation
• Moving-subject tracking
• Equipment inspection
• Outdoor monitoring

3.5-Inch Colour TFT Display

Thermal imagery is presented through a 3.5-inch colour TFT display with 640 × 480 resolution.

The large integrated display provides a convenient viewing interface for inspecting thermal scenes, navigating settings and reviewing captured images.

Five Thermal Colour Palettes

The HT-D9 includes five thermal imaging palettes:

• White Hot
• Black Hot
• Iron Red
• Rainbow
• Cool Colour

Multiple palettes allow different temperature patterns and heat sources to be displayed using different visual representations.

Multi-Scale Detail Enhancement

Integrated multi-scale detail enhancement processes thermal imagery to improve the presentation of important scene details.

The processing system supports improved:

• Edge visibility
• Local contrast
• Small heat-source presentation
• Background separation
• Overall thermal scene detail

Automatic Shutter Correction

The HT-D9 incorporates shutter-based image correction, helping compensate for detector non-uniformity and maintain consistent thermal image quality during operation.

This calibration technology supports stable image presentation during extended thermal observation.

Thermal Image Capture

The HT-D9 supports direct thermal image capture, allowing users to record important thermal observations for later viewing or documentation.

Captured photographs are stored in JPG format, providing compatibility with commonly used computers and mobile devices.

8GB Built-In Storage

The monocular includes 8GB of integrated storage, allowing captured thermal images to be saved directly to the device without requiring separate storage media for standard operation.

Rechargeable 26650 Lithium Battery

The HT-D9 uses a built-in rechargeable 26650 lithium battery, providing portable power for handheld thermal observation.

The rechargeable design eliminates the need for continuous external power during normal portable operation.

Operating Temperature

The HT-D9 is specified for operation between:

Operating Temperature: 0°C to 45°C
Storage Temperature: -20°C to 60°C

These temperature specifications provide clearly defined operating and storage conditions for the thermal imaging system.

Compact Handheld Design

With a listed weight of approximately 556 g, the HT-D9 provides a portable handheld configuration suitable for field observation, inspection and thermal surveying.

Its compact form factor makes it convenient for carrying during outdoor observation and professional inspection work.

Important Use Information

Avoid pointing the thermal detector directly at the sun, welding arcs, lasers or other intense energy sources, as these can damage the thermal sensor.

Keep the lens clean and dry, protect the monocular during transportation and store it within its specified temperature range.
