The phrase "air thermometer" is correct and usable in written English.
It can be used to refer to a device that measures the temperature of the air, often used in meteorology or for indoor climate control.
Example: "The air thermometer indicated a significant drop in temperature as the cold front moved in."
Alternatives: "atmospheric thermometer" or "ambient temperature sensor".
A 1769 illustration of an "electrical air thermometer" from Franklin's Experiments and observations on electricity.
November 30, 1711 Gloucester, England July 4, 1778 Philadelphia, Pennsylvania Ebenezer Kinnersley, (born Nov. 30, 1711, Gloucester, Gloucestershire, Eng. died July 4, 1778, Philadelphia, Pa., U.S.) British colonial contemporary of Benjamin Franklin in the investigation of electricity and inventor of an electrical air thermometer (c. 1755).
Galileo Galilei is most commonly credited, but his clumsy air thermometer, in which a column of air trapped in water expanded when warmed, was the culmination of more than 100 years of improvement.
Keep a digital air thermometer on hand to monitor the temperature.
Almost all airplanes, including single-engine trainers have outside air thermometers.
It was argued, eventually, that if a thermometer was to be reliable, different tokens of the same thermometer type should agree with each other, and the results of air thermometers agreed the most.
Amontons also developed an air-pressure thermometer (1702) and published two notable papers on thermometry (1702 03).
Haynes urgently requested air temperature thermometers to be supplied to all mail planes so that pilots could be warned of possible atmospheric icing conditions, but was forced to operate without them as procurement was to take two months.
(iii) We can use the measurement devices such as vibration sensor, air pressure sensor, thermometer, and automated passenger counting to obtain the data of basic objective parameters of the passenger coaches.
For the BinaxNOW G6PD, the tests were done in the local laboratory facilities, some of which had air conditioning, but thermometers were not always used to guarantee that the ambient temperatures were within the range specified by the manufacturers (18 25°C).
Air-conditioned places cooler than thermometer indicates, because air dry.
