Image Quality and Performance

The 35,200 pixel thermal sensor delivers surprisingly detailed images for the price. The 220x160 resolution reveals more subtle temperature variances compared to lower resolution competitors. This helps identify hidden issues or closely spaced wires and pipes.

The HT-18 accurately detects temperature differences down to 0.1°C. The generous -20°C to 300°C range covers needs from building diagnostics to electrical inspections. The 5 color palette options effectively highlight temperature patterns and contrasts.

The fusion of real-time thermal and visible light images is very useful. You can adjust the balance and overlay position to optimize this blended view. Images are further enhanced by the large, crisp 3.2” LCD display.

The fast refresh rate provides smooth real-time scanning with minimal lag. The lightweight design allows comfortably scanning large areas without fatigue. The pistol-grip handle provides a secure, ergonomic grip.

Ease of Use

Despite its sophisticated capabilities, the HT-18 maintains a simple, intuitive user interface. Large buttons work easily with gloves on. Navigating menus and modes is straightforward. Just point, scan and shoot - critical actions are accessible with the press of a button.

5 pre-configured image modes optimize settings for common applications: building diagnosis, electrical inspection, HVAC, etc. Of course, you can manually fine tune temperature scale, color palette, image blending and other parameters.

Images and video are saved to the 3GB of onboard memory. From there, USB connectivity makes transferring imagery to a computer for archival and analysis easy. The included software extends post-processing capabilities.


While not ruggedized, the HT-18 exhibits solid build quality for a handheld imager. The front lens and screen have durable protective covers. An IP54 rating indicates some resistance to dust and moisture ingress. The hard plastic body should withstand occasional drops and bumps.

The Li-ion battery supports over 4 hours of continuous use. The USB charging port is protected by a removable cover. Overall, the HT-18 delivers reliable performance and is built to handle field use.
