(Greek: measure)

catathermometer, katathermometer
1. An alcohol thermometer, with a dry bulb and a wet bulb, which measures how quickly air is cooling; and so, permitting an estimate of evaporation of moisture from the body.
2. A device consisting of two thermometers, one a dry bulb and the other a wet bulb.

Both are heated to 110°F (43.3°C) and the time required for each thermometer to fall from 100° to 90°F (37.8° to 32.2°C) is noted. The dry bulb gives the cooling power by radiation and convection, the wet bulb by radiation, convection, and evaporation.

From this, the temperature as it affects the body can be deduced; or it is a measure of the heat content of the environment that takes into account air movement as well as temperature.

cathetometer (s) (noun), cathetometers (pl)
An instrument for the accurate measurement of small differences of height; especially, of the differences in the height of the upper surfaces of two columns of mercury or other fluid, or of the same column at different times: The cathetometer consists of a telescopic leveling apparatus, that slides up or down a perpendicular metallic standard which is very finely graduated.

The telescope in the cathetometer is raised or lowered in order to see the objects or surfaces, and to determine the differences in vertical height which are then shown on the graduated standard.

An instrument used to measure the diameter of the uterine cervix.
chorometry (noun) (no pl)
