The Oliso SmartHub is a powerful induction burner that can plug into any power outlet and instantly give you the capabilities of a kitchen range. What makes it revolutionary is the gold plated contact module that allows various SmartTops to dock with the SmartHub so that the two recognize each other and communicate seamlessly within 0.1 degree accuracy without the need for batteries or recharging. The first Oliso SmartTop, the low temperature Precision SmartTop is designed to heat liquid to a precise temperature and keep it there. This allows you to cook sous vide with bags in the traditional manner and allows for precision techniques directly in the bath, making it far more versatile than any other temperature controlled cooker.
