Thermowells protect thermometers and other temperature testing equipment from adverse conditions which they would otherwise be exposed to. A thermowell is a housing the a thermometer threads into, allowing it to be removed from an application without creating a leak in pressure or contaminating the process. Our thermowells are made of the highest quality stainless steel with stem sizes ranging from 2-1/2" to 9" . These thermowells are perfect for brewing beer or cooking of any kind, as well as many other industrial applications.
