An apparatus for measuring or determining the proportion of nitrogen; a nitrometer.

An instrument for measuring the sense of pressure.

An instrument for measuring the sense of pressure. Other forms include: baresthesiometric, baraesthesiometric

An aneroid barometer with diagrams and directions for detecting the existence of a storm at a distance of several hundred miles.

1. A barometer constructed so that it automatically describes the variations in atmospheric pressure.
2. A device that gives a continuous record of barometric pressure.

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.

1. An instrument for measuring the depth of a body of water.
2. A device for ascertaining the depth of water; a bathymeter.
3. An instrument that is used to measure water depth without the use of a sounding line.

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.

1. An instrument for deep-sea sounding or measuring.
2. An instrument for recording contours of deep oceans and seas.

1. The measurement of the depths of oceans, seas, or other large bodies of water.
2. The data derived from such measurement; especially, as compiled in a topographic map.
3. The process of measuring the depths of sea or oceans.
4. The science of measuring ocean depths in order to determine the sea floor topography.

An instrument for detecting photoluminescent signals in marine environments.

The system uses 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.
