A sailor checking the temperature of a ventilation system. Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an electromagnetic field, as in induction heating; where the object is contained in a vacuum or another controlled atmosphere; or in applications where a fast response is required, the accurate surface temperature is desired or ...
Heat guns are used in physics, materials science, chemistry, engineering, and other laboratory and workshop settings.Different types of heat gun operating at different temperatures and with different airflow can be used to strip paint, [1] shrink heat shrink tubing, shrink film, and shrink wrap packaging, dry out damp wood, bend and weld plastic, soften adhesives, and thaw frozen pipes.
Most are used to monitor temperature conditions, and some versions can also measure the relative humidity. Data loggers are often small enough to be placed inside an insulated shipping container or directly attached to a product inside a refrigerator truck or a refrigerated container. These monitor the temperature of the product being shipped.
Temperature is a fundamental parameter in metallurgical furnace operations. Reliable and continuous measurement of the metal temperature is essential for effective control of the operation. Smelting rates can be maximized, slag can be produced at the optimal temperature, fuel consumption is minimized and refractory life may also be lengthened.
A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.
A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.
Modified atmosphere/modified humidity (MA/MH) packaging is a type of equilibrium modified atmosphere packaging (EMAP), which evolved due to the need for more control of humidity in the packaging. Most of the polymers that are commercially used in EMAP are polyolefin -based, characterized by low moisture vapor transmission rate (MVTR).
A time temperature indicator (TTI) is a device or smart label that shows the accumulated time-temperature history of a product. Time temperature indicators are commonly used on food , pharmaceutical , and medical products to indicate exposure to excessive temperature (and time at temperature).
