The ITI SF Gas Thermal Imager series, featuring the SF320 and SF640 models, is engineered for precise gas leak detection utilizing a QWIP detector with infrared resolutions up to 640x512. These imagers operate within a 10.3 to 10.8 µm spectral range and deliver high thermal sensitivity below 0.025°C.
Equipped with a 5.8-inch sunlight-visible capacitive touchscreen, a built-in color viewfinder, and a 5-megapixel digital camera with an LED light, the units offer advanced analysis tools including image fusion, IMIX, and super-resolution. They are powered by a removable rechargeable lithium battery providing over two hours of operation and include a 32G high-speed SD card alongside optional GPS positioning.
