Chapter Five - Definitions Flashcards
What is infrared thermometers?
Devices that measure temperature, using black body radiation emitted from objects.
Wha is a magnetic surface contact thermometer?
One of the most common instruments used to determine substrate temperature.
What is a psychometric table?
Booklet used to determine the relative humidity and dew-point temperature of the air.
What is relative humidity?
The ratio, expressed as a percentage, of the amount of water vapour present in a given volume of air at a given temperature to the amount required to saturate the air at that temperature.
What is repeatability?
The ability of the instrument to give the same readings under similar ambient and target conditions.
What is a sling psychrometer?
The type of psychrometer most used in coating inspection. It is used to measure the ambient air temperature to calculate dew point and relative humidity
What is a wind speed monitor?
An instrument to help decide if conditions are appropriate for coating application projects.
What is dew point?
The temperature at which moisture will begin to form on a steel surface.
