How It Works

How it Works

Core is best

How Our Scanners Work
A special artery, the Temporal Artery, runs directly from your heart to your forehead, naturally emitting the body’s core temperature. Because it reads the blood flowing from your heart, the Temporal Artery reading is considered the best way to determine body temperature.

We Thought of Everything
We created and patented the Arterial Heat Balance system.  It ensures every reading is fully accurate by mathematically accounting for ambient temperatures and the cooling effect of the scanner.

Another key part of getting an accurate read is our scanner doesn’t take just one measurement. Our scanners take 1,000 readings per second to ensure you get the right reading.

And Then Some
The caliber thermometer we wanted needed a technology that didn’t exist. So we invented our own. We created 10 different patented technologies tested in more than 70 medical trials as part of our Temporal Artery Thermometers.
