Definition - What does Hydroscopic mean?

Hydroscopic refers to ability of using a hydroscope to view and obtain images of objects underwater. This enables people to see objects which are far below the surface of water. This technique of looking things underwater is called hydroscopy. The word hydroscope is used to refer to any instrument related to water. This could, for example, be a long tube fitted with various lenses.

Petropedia explains Hydroscopic

Hydroscopic makes use of a hydroscope which is one of several instruments that combines electronic or optical analysis of physical properties with water. In ancient times, this meant a kind of nautical telescope that was aimed downward, for observation and projection of underwater images to a screen.

One type of hydroscope is a benchtop piece of laboratory equipment that measures the presence and qualities of many liquid variables, including:

  • Emulsification
  • Phasing of multiple liquids
  • Saturation points
  • Viscosities
  • Mixing effects of different inks

This equipment might resemble a box with sensors and an electronic readout interface.

Applications of hydroscopy typically include emulsification tests for ink/water balances for printing presses. Generally, hydroscope designs may serve to make clear observations of a fluid medium; others may also serve to detect the presence of water in air.
