Number of the sensor's measurement points, shown to the catalog's scale.
The largest sensor in the database has 327 680 points.
Published by the manufacturer
A recurring marketing mix-up at this manufacturer. Several retailer listings for the closely related HT-18 model advertise an infrared sensor of "640 x 480", which is actually the resolution of the built-in VISIBLE CAMERA, while the screen itself displays 320 x 240. This confusion between the thermal sensor, the visible sensor, and the screen runs across the manufacturer's entire lineup.

Observations
For this specific model, the 220 x 160 thermal sensor is confirmed by several independent listings, but none of them publish the IFOV.
Roughly 3 GB of internal memory, with no removable card.
Continuously adjustable emissivity, but no source documents reflected-temperature correction.
