The SD250 is the truly superior economy thermal imager with Universal Viewing System that enables easy and clear viewing of the display in all environmental conditions and designed with essential safety features that provides unbeatable cost-performance ratio. It comprises of the latest 160 x 120 resolution Eco-Clear sensor technology, delivering ultra high Range to Sensitivity (R:S) Ratio with a value of 8,800 and outstanding sensitivity value of 100 mK (nominal). This results in ultimate clarity and dynamic range capability in normal or firefighting modes, meaning more headroom for clear imaging at extreme temperature ranges. The more you can see in these extreme situations, the safer you are. The Thousand Plus operating mode takes you beyond the simple two modes that other TICs offer, imaging above 1,000 °C scene temperatures which assists recognition of an impending flashover or backdraft, and with the enhancement of ICETM enables firefighters to see hot objects and cooler surroundings simultaneously – the extra information is vital for making best-informed decisions – learn more about ICETM The simplicity of single button, fully automatic operation allows the firefighter to concentrate on fighting fires. Combining this with ISG’s ultimate imaging performance and extra headroom equates to a breakthrough in Firefighter Safety.
