Professional Precision Meets Rugged Reliability.
The Hti-Xintai HT-18+ (the newly upgraded version of the popular GW256) is a high-performance handheld infrared thermography camera designed for professionals who can’t afford to miss a detail. Featuring a crisp 256 x 192 IR resolution and Dual-Light Fusion technology, this tool allows you to see the world in a way the naked eye simply can’t.

Whether you are hunting for hidden water leaks, diagnosing an overheating electrical panel, or auditing home energy efficiency, the HT-18+ provides the clarity and data you need to make informed decisions. With a wide temperature range of -4°F to 1022°F and advanced thermal sensitivity, it’s the ultimate diagnostic partner for HVAC technicians, electricians, and building inspectors.

Key Features :
-
[New Model HT-18+] Improved Performance: Rest assured you are getting the latest hardware. The HT-18+ replaces the GW256, offering the same trusted reliability with optimized internal processing for smoother thermal imaging.
-
Superior 256x192 IR Resolution: Stop squinting at blurry images. With 49,152 pixels and a high thermal sensitivity of 40mk, you get crystal-clear thermograms that identify even the smallest temperature fluctuations.
-
Innovative Dual-Light Fusion: Overlay standard visual images onto thermal data. This allows you to see exactly which component is failing by combining real-world outlines with heat signatures for easier troubleshooting.
-
Wide Temperature Range & Accuracy: Measure from -20°C to 550°C (-4°F to 1022°F) with an accuracy of ±2°C. Perfect for everything from cold-storage diagnostics to high-heat industrial machinery.
-
Full Video & Photo Analysis: Capture JPG photos and MP4 videos directly on the device. Transfer data via USB to the included PC Analysis Software to create professional reports for your clients.
-
Built for the Job Site: Featuring an IP54 rating (water/dust resistant) and a rugged design tested for 2-meter drops, the HT-18+ is built to survive crawlspaces, attics, and busy factory floors.

Detailed Industry Applications
-
HVAC & Energy Audits: Quickly identify insulation gaps, ductwork leaks, and malfunctioning underfloor heating systems.
-
Electrical Maintenance: Safely detect overheating breakers, loose connections, and imbalanced loads before they cause a fire or system failure.
-
Plumbing & Leak Detection: Find hidden pipe bursts or moisture buildup behind walls without needing to perform invasive "search and destroy" demolition.
-
Mechanical & Automotive: Monitor bearing friction, cooling system blockages, and engine misfires by tracking real-time heat signatures.
-
Agriculture & Veterinary: Use the high-sensitivity sensor to monitor animal health or inspect greenhouse climate control systems.

PCB
Use the HT-18+ to quickly detect hot spots, overheating areas, and potential failures on your PCB and help determine the best heat dissipation solution for your device.
Floor heating pipe
The HT-18+ can detect uneven cooling or heating in underfloor heating lines by capturing images of heat distribution to help technicians identify problems and fix them.

Auto Repair
Thermal analysis of the engine, thermal analysis of the vehicle exhaust system, thermal analysis of heat transfer, thermal analysis and fault diagnosis of the brake system, thermal effect analysis of the tire and thermal analysis of the air conditioning system.

Security monitoring
Thermal imaging cameras can detect the heat of objects such as humans, animals and vehicles, so they can be used for security surveillance, such as monitoring public places and foreign borders.

Machine
Users can scan electric water heaters, electrical cabinets, components, and detect a large number of wires and connectors, and immediately understand the problem. The problem area can be detected and fixed before the problem actually occurs.

Engine fault detection
Infrared thermography allows you to identify engine faults by looking at the temperature changes on the engine surface. Each piston and cylinder wall of an engine varies in temperature and if an area is too hot or too cold, there is a fault in that area.

Electrical
There are many kinds of faults of electric equipment, but most of them are accompanied by heating. In the power industry, infrared thermal imagers have been used for the safety inspection of equipment for a long time.

Frequently Asked Questions (FAQ)
Q: Is the HT-18+ different from the GW256? A: The HT-18+ is the official successor to the GW256. It features the same high-resolution 256x192 sensor but includes updated branding and optimized software for better performance. If you were looking for the GW256, the HT-18+ is the correct, newest version to purchase.
Q: Does it come with software for professional reports? A: Yes! The package includes Thermal Imaging Image Analysis Software for PC, allowing you to analyze saved data, adjust palettes, and generate professional PDF reports for your customers.
Q: Can I see through walls with this camera? A: Thermal cameras cannot see "through" solid objects. However, they detect the heat signature on the surface of the wall. For example, if a hot water pipe is leaking behind drywall, the heat will conduct to the surface, and the HT-18+ will clearly show the leak pattern.
Q: How do I transfer my photos and videos? A: Simply connect the camera to your PC or Mac using the included USB cable. The device acts like a flash drive, allowing you to drag and drop your JPG and MP4 files instantly.
