(Greek: measure)

psychrometry
1. The study of the physical laws that influence air and water mixture.
2. The calculation of relative humidity and water vapor pressures from wet and dry bulb temperatures and barometric pressure; whereas relative humidity is the value ordinarily employed, the vapor pressure is the measurement of physiological significance.
pulmometer
pulmometry
pulsimeter (s) (noun), pulsimeters (pl)
1. An instrument for indicating and registering the frequency, force, and variations of the pulse.
2. An instrument which, when applied over a blood artery, graphically indicates the movement or type of pulse.
pupillometer
An instrument for recording pupillary diameter.
pupillometry
The recording of the pupillary diameter of the eye.
pupillostatometer
1. A device for measuring the interpupillary distance.
2. An instrument for measuring the distance between the centers of the pupils of the eyes.
pyelometer
pyelometry
pyknometer, pycnometer
A graduated glass vessel used to measure the relative density (thickness) of fluids.
pyknometry, pycnometry
The measurement of the relative density (thickness) of fluids by using a pykonometer.
pyrgeometer
1. Measuring effective terrestrial radiation or long wave, or infra-red, radiation originating by thermal emission from the earth's surface and/or its atmosphere which is distinguished from solar radiation.
2. An instrument that measures radiation from the earth's surface transmitted into space.
pyrheliometer
1. An apparatus for measuring the heating effects of the sun.
2. An instrument that measures the intensity of direct solar radiation.
3. A general term for the class of actinometers (name for any instrument used to measure the intensity of radiant energy, particularly that of the sun) that measure the intensity of direct solar radiation.
4. An instrument that measures the total intensity of direct solar radiation received by the earth.

Actinometers may be classified, accordingly to the quantities that they measure, in the following manner:

  • Pyrheliometer, which measures the intensity of direct solar radiation.
  • Pyranometer, which measures global radiation (the combined intensity of direct solar radiation and diffuse sky radiation)
  • Pyrgeometer, which measures the effective terrestrial radiation.
pyrometer
An instrument for measuring high temperatures.
pyrometry
A field of technology concerned with the measurement of high temperatures.
