Temperatures around zero degrees and dangerous wind chills mean it’s even more important to bundle up if you’re going outside.
The Wausau Fire Department’s thermal imager device can measure how much heat our bodies lose in cold temperatures. The thermal imager is used to translate heat into visible light. The device is used by frequently used by firefighters to find a heat source.
“What it does is it senses radiant heat, either from the body or any type of heat source,” said Derek Pionke, engineer for the Wausau Fire Department.
During an experiment, Pionkee stood outside in -2 degree weather to test the thermal imager. He started off layered up and the thermal imager showed heat leaving mostly from his head and hands.
