The item in the image is a handheld thermal imaging camera, likely the Hti HT-18 or HT-18+ model. Technology: It integrates surface temperature measurement with real-time thermal image generation, displaying both on a color screen. Resolution: Models in this series feature high infrared resolutions, such as \(256\times 192\) pixels. Temperature Range: Typically capable of measuring temperatures ranging from \(-20^{\circ }\text{C}\) to \(300^{\circ }\text{C}\) (or \(-4^{\circ }\text{F}\) to \(1022^{\circ }\text{F}\)). Applications: Useful for home inspections, HVAC diagnostics, electrical troubleshooting, and mechanical assessments.
