Testo 882: Thermal imager with 320 × 240 pixels and NETD < 60 mK

摘要

Thermal imagers measure the infrared energy emitted by surfaces remotely. The Infrared energy emitted by the object is focused on to an infrared detector. By the laws of Physics the Infrared energy emitted by the object is related to the temperature of the object. The Thermal Imager converts this infrared energy into a heat picture of the object which in thermal Imaging Terminology is known as a Thermogram. Different temperatures in the Thermogram are represented by different colors.
