Hydrometers

Usually the density is determined, prefereably in the units g/cm³, kg/m³ and g/ml.

With alcoholometers usually the content of alcohol by volume in ethanol-water mixtures are determined.

Reference temperature is 20°C. Other reference temperatures are possible.

Calibration is generally made for 'reading below', for non-transparent liquids also 'reading above'.

Available in the following types:

		density hydrometers, standard
		density hydrometers, DIN
		hydrometers, ASTM
		Hydrometers, BS 718
		hydrometers for mineraloil, liquified gas, milk, water
		hydrometers, Baumé und Brix
		alcoholometers
		hydrometers for special applications
