The ITI FIR series comprises science-grade infrared thermal imagers, including the FIR 384, FIR 640, and FIR 1024 models, engineered for precise temperature measurement and thermal analysis. These cameras utilize uncooled focal plane array detectors with amorphous silicon or VOX materials across an 8 μm to 14 μm spectral range, offering infrared resolutions up to 1024x768 and thermal sensitivities down to ≤ 0.04°C. They support manual, electric, and automatic focus with interchangeable lens options ranging from 6° to 48° fields of view, alongside macro lenses for specialized close-up tasks.

Housed in a compact enclosure measuring 226.8 mm × 91 mm × 86.5 mm and weighing under 1 kg, the cameras feature standard 100/1000M Ethernet transmission for real-time total radiation temperature data streams. They operate within a standard temperature range of −40°C to +410°C (with optional high-temperature ranges up to +2000°C) at an accuracy of ±2°C or ±2%. Designed for rigorous environments, the units include flexible networking and power options, optional synchronous triggers, and comprehensive PC software support for advanced data analysis.
