The iVario's fast, even and precise heating is accomplished via patented heating technology. The iVario uses ceramic heating elements attached to a durable heat-conductive, scratch-resistant pan base designed to withstand extreme temperature swings and heavy everyday use. The iVario pan base reaches 400°F in less than three minutes, and can reduce the temperature with similar speed. Numerous sensors measure the pan base every second to adjust temperatures for consistent results and energy efficiency.
