Noun
kata thermometer (plural kata thermometers)
- (measuring instrument) A device consisting principally of an alcohol thermometer, used to measure air cooling power and, indirectly, small wind speeds in circulating air, by measuring the time taken for the temperature of the bulb of alcohol to make a specified drop (100° to 95°F).

- Though the kata-thermometer was originally designed for measuring human comfort, it afterwards turned out to be far more useful as an anemometer.

[…] The Kata thermometer provides a good general measure of air velocity; however, in fluctuating air the variation in air velocity will affect human response and should be quantified.
