This product which initially could be considered a gadget finds use everywhere. Acquired in a food order after washing seen used in a large restaurant, he didnt like him to indicate in a record time the temperature of the furnace, water cooking pot or the verification of the ideal temperature of the fridge. But it may prove to be useful in many circumstances: DIY, monitoring of the bath etc. Its use is very simple, its weight is light and sufficiently large range. My husband is eager to try it for the traditional cooking of foie gras from year end!
