An apparatus for measuring or determining the proportion of nitrogen; a nitrometer.
baresthesiometer, baraesthesiometer (s) (noun)
; baresthesiometers; baraesthesiometers (pl)
An instrument for measuring a person's pressure senses or sensitivities of weights or pressures: Dr. Robertson, the neurologist, used a baresthesiometer while diagnosing Wendy's reaction to physical pressure.
baresthesiometric, baraesthesiometric (adjective)
; more baresthesiometric, most baresthesiometric; more baraesthesiometric, most baraesthesiometric
A reference to an instrument for measuring the sense of bodily pressures: The baraesthesiometric pressure of a single feather can be accurately measured on the scale.
An aneroid barometer with diagrams and directions for detecting the existence of a storm at a distance of several hundred miles.
barograph (s) (noun)
, barographs (pl)
A barometer that is constructed so that it automatically describes the variations in atmospheric pressures: Since barographs produce descriptions of atmospheric pressures, they may be used to record elevation changes during aircraft flights.
In medicine, a device for measuring the weight and length of infants.
1. An instrument for measuring atmospheric pressure; used in determining height above sea level and predicting changes in the weather.
2. Anything that reflects or indicates change; such as, breadlines are a barometer of unemployment.
The science that deals with the use of the barometer and making barometric observations.
The scientific study of the measurement of atmospheric pressure.
bathometer, bathymeter (s) (noun)
; bathometers; bathymeters (pl)
An instrument for measuring the depth of a body of water: In her oceanography class at college, Susan learned that a bathometer
was used to ascertain the depth of the sea, but it is rarely used in the present time.
A sounding line was used previously with a bathymeter, but it proved to be quite difficult and a time-consuming procedure.
The bathometer does not require a line to extend to the bottom because it measures the difference in the gravitational effect of the water surface and of solid ground.
bathymeter (s) (noun)
, bathymeters (pl)
1. An instrument for recording contours of deep oceans: Besides being used for deep-sea sounding and measuring, a bathymeter is also good for finding out the topography of the bottom surface of the seas.
2. A simple device used for gaging the deepness of liquids in tanks and wells: Mr. Smart used a bathymeter to find out how much water was left in his waterhole on the farm.
bathymetry (s) (noun)
, bathymetries (pl)
1. The measurement of the depths of oceans, seas, or other large bodies of water: Since Thomas was interested in oceanography, he learned more about bathymetry and found out that it was the underwater equivalent to "hypsometry" or "topography".
2. The data derived from such measurements: The material obtained from bathymetry, and compiled in a topographic map, provides good information for navigation.
3. The science of measuring ocean depths in order to determine the sea floor topography: Judy decided to study bathymetry, since she was very interested in oceanography and vessels.
bathyphotometer (s) (noun)
, bathyphotometers (pl)
An instrument for detecting photoluminescent signals in marine environments: A bathyphotometer
integrates the system of using photodiodes to convert the optical signals into electrical signals which are sampled, integrated, and coupled to output terminals for transmission to a surface host vehicle.
Here is more information about bathyphotometry.
1. A device for measuring carbon dioxide given off by organisms and, hence, for determining the quantity of living matter present.
2. An instrument by which minute quantities of carbon dioxide can be measured; used in measuring the carbon dioxide given off from functioning tissue.
