  • Page 6: Measurement Principle

    1.3 Measurement principle The Hygrovision mini analyzer registers the dew point of water or hydrocarbons in a gaseous mixture according to the principle of direct measurement, utilizing a mirror that can be heated and cooled. The measurement process involves monitoring the surface of the mirror and noting the tem- perature at the moment condensation forms on its surface.
  • Page 7 (battery), and a four-button control unit (button pad). Via the four-button control pad, the electronics unit makes it possible for the Hygrovision mini user to control how rapidly the condensation mirror is cooled and heated. The button pad is also used to turn the analyzer on and off, select the illumination system, and enter other operating commands.

    2.3.2 Visual identification of water condensation Illustration 18 Illustration 19 When using the Hygrovision mini, the operator can observe the condensation of water vapor utilizing either side lighting or vertical lighting. Under side lighting, the dark surface of the mirror appears to become evenly covered with red spots as condensation forms (illustration 18).

  • Page 29: 3! Visual Identification Of Hydrocarbon Condensation

    Illustration 23 Illustration 22 Under side lighting, the ice crystals that form appear as clear luminous red patches when viewed through the microscope (illustration 22). Under vertical lighting, the ice crystals that form appear as branching dark patches on a light background when viewed through the microscope (illustration 23). 2.3.3 Visual identification of hydrocarbon condensation The condensation of hydrocarbons (HCs) can only be observed under vertical lighting.
  • Page 30 Illustration 26 Illustration 25 Octane and higher hydrocarbons condense on the surface of the mirror in the form of small, dilute dark spots. As the mirror continues to cool, these small spots slowly form into droplets (illustration 26). As the cooling process continues, the small condensation droplets slowly collect to more completely cover the mirror’s surface, until it becomes noticeably darkened.

When taking water dew point measurements in automatic cooling mode, push the Down button to fix the temperature at which condensation occurs, and to fix the tem- perature at which evaporation occurs push the Up button. The dew point value will be calculated as the mean of these two temperatures (the condensation and evaporation points) in automatic cooling mode and shown on the analyzer’s display.
