A Meker–Fisher burner, or Meker burner, is an ambient air laboratory burner that produces multiple open gas flames, used for heating, sterilization, and combustion.It is used when laboratory work requires a hotter flame than attainable using a Bunsen burner, or used when a larger-diameter flame is desired, such as with an inoculation loop or in some glassblowing operations.
Thermocouple. A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature.
Dry / Wet-bulb temperature. v. t. e. Psychrometrics (or psychrometry, from Greek ψυχρόν (psuchron) 'cold' and μέτρον (metron) 'means of measurement'; [1][2] also called hygrometry) is the field of engineering concerned with the physical and thermodynamic properties of gas - vapor mixtures.
A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. [1] Heat is generated by the passage of electric current through a resistor through a process known as Joule Heating. Heating elements are used in household appliances, industrial equipment, and scientific ...
The thermal boundary layer thickness is customarily defined as the point in the boundary layer, , where the temperature reaches 99% of the free stream value : such that = 0.99. at a position along the wall. In a real fluid, this quantity can be estimated by measuring the temperature profile at a position along the wall.
Piezoelectricity (/ ˌpiːzoʊ -, ˌpiːtsoʊ -, paɪˌiːzoʊ -/, US: / piˌeɪzoʊ -, piˌeɪtsoʊ -/) [ 1 ] is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins —in response to applied mechanical stress.

A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical reaction made in a thin zone. [1] When flames are hot enough to have ionized gaseous components of sufficient density, they are then considered plasma. [vague][2]
A Rubens tube setup. A Rubens tube, also known as a standing wave flame tube, or simply flame tube, is a physics apparatus for demonstrating acoustic standing waves in a tube. Invented by German physicist Heinrich Rubens in 1905, it graphically shows the relationship between sound waves and sound pressure, as a primitive oscilloscope.
