IR - Thermal Imaging System

Scans the Temperature profile of thearea being focused

Generates a Coloured thermal image ofthe area being focused on the view -finder

Colour profile indicates the temperatureprofile of the area

IR - Thermal Imaging System

The temperature at any spot of the areacan be measured in the camera view

finder ( Field measurement )Also the thermal image can be stored in

inbuilt floppy disc / PCMC Card

The image can subsequently beanalysed in the computer
