ThermoWorks The Original Cooking Thermometer/Timer : The TW362B has a robust design and a slide switch so the unit can be powered off. The well-loved simplicity means you won’t need to find the instructions each time you set an alarm. The stylish housing folds the display up for counter use or flat for less obtrusive magnetic mounting to an appliance door. This is a huge kitchen favourite in commercial and home kitchens as well as industrial and lab use.
