Anemometer An anemometer is a device used for measuring wind speed, and is a common weather station instrument. The term is derived from the Greek word anemos ,which means wind, and is used to describe any wind speed measurement instrument used in meteorology. The first known description of an anemometer given by Leon Battista Alberti in 1450.

What Is a Hygrometer and How Does It Work? A hygrometer is weather instrument used to measure the amount of humidity in the atmosphere. There are two main types of hygrometers – a dry and wet bulb psychrometer and a mechanical hygrometer. What is Humidity? Humidity is the amount of water vapor in the atmosphere caused by condensation and evaporation. It can be measured as absolute humidity (the amount of water vapor in a unit volume of air), or as relative humidity (the ratio of moisture in the atmosphere to the maximum moisture the atmosphere can hold). 1  It is what gives you that horrible sticky feeling on a hot day and can cause heat stroke.

Anemometer The cup anemometer (used in weather stations) measures the velocity in a plane perpendicular to the axis of its rotation cups. If the cup anemometer is mounted with the shaft perpendicular to the horizontal, it will measure only the component of the wind that is parallel to the ground.

hydrometer hydrometer (hīdrŏm´ətər), device used to determine directly the specific gravity of a liquid. It usually consists of a thin glass tube closed at both ends, with one end enlarged into a bulb that contains fine lead shot or mercury to cause the instrument to float upright in a liquid.

What Is Humidity And How Does It Affect Life On Earth? A hygrometer or a psychrometer is used to measure humidity. A psychrometer employs the use of two thermometers to measure relative humidity accurately. The thermometers simultaneously measure the wet-bulb and dry-bulb temperatures. A common device used to measure relative humidity by meteorologists is the sling psychrometer which is swung around.

- A tonometer is the medical term for the instrument used to measure  the pressure in the eye to detect glaucoma. The tonometer shoots a  blast of air into the eye, directly i…nto the pupil. A tonometer is used to measure eye pressure.

- To measure arterial blood pressure, the cuff of the sphygmomanometer is usually wrapped around the arm so that it surrounds the brachial artery. Air is pumped into the cuff until the cuff pressure exceeds the pressure in that artery.As a result, the vessel is squeezed closed, and its blood flow stopped.hen the cuff pressure is approximately equal to the systolic blood pressure within the brachial artery, the artery opens enough for a small amount of blood to spurt through. This movement produces a sharp sound (Korotkoff's sound) that can be heard through the stethoscope.

Magnetometer This system is composed of a vector helium and fluxgate magnetometers. Magnetometers were also a component instrument on the Mercury MESSENGER mission. A magnetometer can also be used by satellites like GOES to measure both the magnitude and direction of the magnetic field of a planet or moon.aussmeters and teslameters are magnetometers that measure in units of gauss or tesla, respectively. In some contexts, magnetometer is the term used for an instrument that measures fields of less than 1 millitesla (mT) and gaussmeter is used for those measuring greater than 1 mT.

Sphygmomanometer Clinical mercury Manometer. A sphygmomanometer, blood pressure meter, blood pressure monitor, or blood pressure gauge is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, and a mercury or mechanical manometer to measure the pressure.

hydrometer A hydrometer or areometer is an instrument that measures the specific gravity (relative density) of liquids—the ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass, and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. The liquid to test is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely. The point at which the surface of the liquid touches the stem of the hydrometer correlates to specific gravity.

How Is Blood Pressure Measured and What Do the Numbers Mean? Measuring Blood Pressure. Blood pressure is measured with an instrument called a sphygmomanometer. First, a cuff is placed around your arm and inflated with a pump until the circulation is cut off.

Anemometer An anemometer is a device for measuring wind speed, and is a common weather station instrument. The term is derived from the Greek word anemos, meaning wind. The first known description of an anemometer was given by Leon Battista Alberti around 1450. Cup anemometers: Simple type of anemometer is the cup anemometer, invented (1846) by Dr. John Thomas Romney Robinson, of Armagh Observatory. 2  It consisted of four hemispherical cups.

sphygmomanometer A sphygmomanometer that allows the blood pressure to be taken without the observer's knowing where zero pressure is on the device. After the pressure is obtained, the mercury comes to rest at a point. The observed pressure is then corrected by subtracting the at-rest value on the device from the pressure obtained.

- As noted, the sphygmomanometer has become, if not the gold standard, at least the default option for blood pressure measurement, even though that method cannot in any sense be regarded as having final validity, that is in some ultimate sense of measuring real blood pressure.

sphygmomanometer The pressure is estimated by means of a mercury or an aneroid manometer. A stethoscope is normally used in conjunction with the instrument to listen to the blood pressure sounds (a stethoscope is not needed with an electronic sphygmomanometer).

Sphygmomanometer 1 It is possible to obtain a basic reading through palpation alone, but this only yields the systolic pressure. 2  Mercury sphygmomanometers are considered to be the gold standard. 3  They measure blood pressure by observing the height of a column of mercury, which do not require recalibration.

Instruments A hygrometer is an instrument used to measure relative humidity. Humidity is the measure of the amount of moisture in the air. A psychrometer is an example of a hygrometer. A psychrometer uses two thermometers to measure relative humidity; one measures the dry-bulb temperature and the other measures the wet-bulb temperature.

Nitrile Chemical-Resistant Gloves It offers excellent physical-hazard resistance to punctures, cuts, snags and abrasion. Nitrile rubber has considerable resistance to oils, fuels, and certain organic solvents. It is commonly used as a coating for dipped gloves and also in the construction of laminated, impregnated cut-and-sewn gloves.

5.4 What equipment is needed to measure a patientâs blood pressure? B Portable aneroid sphygmomanometer. (1) Bladder. The bladder (also called the “cuff”) is a long rubber bag about 6 inches wide and 24 inches long that is covered with fabric. The bladder is wrapped around the patient’s arm and filled with air when taking the patient’s blood pressure. Parts of the fabric are made of non-slip material, such as Velcro.
