TVS 7B Highly sensitive compact thermal vision device allows transformation of invisible infrared images into visible image, observed through a bi-ocular (one sensor - two visual channels). Viewing with both eyes provides better image perception and comfort for user. The unit is fully waterproof and can be used under severe environmental conditions. Some of the tasks suitable for the instrument are: - Search and rescue - Hunting and animals observation - Industrial research and process control - Inspection of thermal insulations in residential and industrial buildings - Inspection of high voltage transmission lines TVS 7B uses a modern linear array detector and low noise electro magnetic scanner. Coupled with optimal electronic processing of the signal this has allowed realistic capacity to detect temperature difference of below 0.1 °K. The product does not suffer from long inertia in image displaying, which is typical to commonly used thermal imagers based on bolometric arrays. Therefore, high image quality and resolution doesn't degrade when you are surveying the terrain with high angular velocity. The device is built to fit military requirements.         Specifications Spectral diapason, mkm Magnification Image format, pixels Field of view (vertical x horizontal), degrees Spatial resolution, mrad Temperature resolution, °C Detection distance (standing human), m Recognition distance (standing human), m Power consumption, Watt Working temperature range, °C Battery life for continuous work without recharge, hours Battery type Focus range, m Dimensions, mm Weight with battery, kg     3-5 3 128x256 2.7x3.8 0.5 0.1 1,500 700 6 -40 - +55 2 Sony lithium, rechargeable 8 - infinity 260x145x86 1.6
