Product Description

The HT-A2+ Touch Screen Thermal Imager is a compact professional thermal imaging camera featuring 256×192 infrared resolution, a 3.2-inch touchscreen, -20°C to 550°C temperature measurement range, adjustable emissivity and multiple thermal colour palettes. It is designed for non-contact thermal inspection, troubleshooting, preventive maintenance and temperature analysis.

Product Overview

The HT-A2+ Touch Screen Thermal Imager combines infrared thermal imaging with a compact handheld design for rapid identification of temperature differences and thermal abnormalities.

Its 256×192 infrared detector provides detailed thermal images, while the 3.2-inch touchscreen allows convenient navigation and adjustment of measurement parameters. With a 56° × 42° field of view, the camera provides a wide perspective for inspecting equipment, building surfaces and other targets.

The HT-A2+ supports multiple thermal display palettes, adjustable emissivity and measurement modes including centre-point measurement and hot/cold spot tracking. It can also display infrared, visible-light and combined thermal/visible images.
