What's the difference between hydrometer and thermometer?

Hydrometer


Definition:

  • (n.) An instrument for determining the specific gravities of liquids, and thence the strength spirituous liquors, saline solutions, etc.
  • (n.) An instrument, variously constructed, used for measuring the velocity or discharge of water, as in rivers, from reservoirs, etc., and called by various specific names according to its construction or use, as tachometer, rheometer, hydrometer, pendulum, etc.; a current gauge.

Example Sentences:

  • (1) The following noninvasive measuring methods were used for evaluation of the skin before and after exposure to irritants: measurement of transepidermal water loss by an evaporimeter, measurement of electrical conductance by a hydrometer, measurement of skin blood flow by laser Doppler flowmetry, measurement of skin colour by a colorimeter and measurement of skin thickness by ultrasound A-scan.
  • (2) The concentration of solids (or water) in urine can be measured by weighing, hydrometer, refractometry, surface tension, osmolality, a reagent strip, or oscillations of a capillary tube.
  • (3) the Skicon-100 and Corneometer CM 420 hydrometers and the Servo Med EPI evaporimeter.
  • (4) In an attempt to analyze the "texture match" of grafted skin, functional and morphological aspects of the stratum corneum were studied using the Skin Surface Hydrometer (IBS Inc.) and the scanning electron microscope.
  • (5) In conclusion, both hydrometers were deemed relevant and valid for assessment of skin moisture.
  • (6) Specific gravity of the colostrum was measured using a hydrometer in increments of 5 degrees C from 0 to 40 degrees C. Specific gravity explained 76% of the variation in colostral total IgG at a colostrum temperature of 20 degrees C. The regression model was improved only slightly with the addition of protein, fat, and total solids.

Thermometer


Definition:

  • (n.) An instrument for measuring temperature, founded on the principle that changes of temperature in bodies are accompained by proportional changes in their volumes or dimensions.

Example Sentences:

  • (1) Using a meat thermometer, with the probe inside the thickest part of the cut, can ensure that you get it right every time.
  • (2) In both clincis phenylmercuric borate was used for desinfection of the thermometers.
  • (3) In a prospective, blinded trial, 40 healthy adult subjects using six IRED thermometers with two techniques were examined in random sequence.
  • (4) Soft organic material (meat, cucumber peels) was found in four patients, chicken bones in six, pins and needles in six, other nonorganic materials (toys, stone, broken thermometer) in six.
  • (5) At the same time, another health professional used a digital electronic thermometer to measure the temperature at each site and a special rectal probe to measure core temperature.
  • (6) To butcher TS Eliot: I have seen the mercury of my thermometer flicker, And I have seen the eternal footman hold my sheets drenched in sweat at 3am, and snicker, And in short, I was too hot.
  • (7) In the situation where accurate measurement of temperature by thermometer is not available, mother's assessment about presence or absence of fever in her child can be relied upon by health-workers and physicians.
  • (8) Time dependence of the surface temperature at the centre of the target area immediately after exposure and the spatial distribution of the surface temperature around the target area during exposures were measured using a thermocouple thermometer.
  • (9) Besides according to clinical manifestations, the therapeutic effect was objectivized in dynamics through the oscillography "Gesenius-Keller", double-rheography "Schufrid", skin thermometer--Tastotherm P 60 "Braun" and 6-canal ECG apparatus "Hellige".
  • (10) This nosocomial outbreak of infection due to a highly vancomycin-resistant strain of Enterococcus is the first epidemic in which an electronic thermometer has been implicated as the vehicle of transmission for an infectious agent.
  • (11) The Craftemp thermometer is an electrical device for measurement of oral and axillary temperatures.
  • (12) We studied two infrared thermometers (FirstTemp and Thermoscan) and a thermistor (IVAC) in children with cancer.
  • (13) The infrared tympanic thermometer tracked the core temperature (as measured by the thermistor tip of the pulmonary artery catheter) closely, with a correlation coefficient of 0.98, and took less than 2 sec to measure.
  • (14) Nasal mucosal temperature was measured in 71 healthy subjects with an electronic thermometer.
  • (15) This report describes a 23-year-old white man who injected metallic mercury from a thermometer into his antecubital vein in an attempt at suicide.
  • (16) For use on unconscious patients or those who are otherwise unwilling or unable to cooperate with traditional techniques, IR ear thermometers offer a more comfortable and less stressful method of temperature taking for both patients and nurses, especially where rectal temperatures are used.
  • (17) Each cell in the thermometer contains liquid crystals with a slightly different makeup so they reflect the same wavelength of light at just slightly different temperatures.
  • (18) The CDC issued guidance on the scanners, calling them “less precise” than other temperature-taking measures , such as traditional mercury thermometers, and acknowledging that their effectiveness can be impacted by ambient temperatures.
  • (19) To determine if a tympanic membrane thermometer is of benefit on a pediatric unit.
  • (20) A mathematical model has been developed to determine the spatial resolving power of these thermometers.
