Hydrogen Bubble Flow Visualisation System

Hydrogen Bubble Flow Visualisation System for Educational Laboratory.

Product Code:

Hydrogen Bubble Flow Visualisation System

    A compact, bench mounted, self- contained unit used for flow visualisation studies using water as the working fluid.
    The unit comprises a flow tank incorporating the working section and pumped recirculation system, plus a separate electronic control console.
    A low voltage variable speed pump with a unique fluid-drive unit is located under the working section.
    The electronic control console incorporates manual controls and a 4 line, 20 digit LCD that displays the relevant operating parameters.
    Flow patterns in the water are indicated by small hydrogen bubbles that are generated by an interchangeable fine platinum/ iridium wire cathode.
    A low voltage light source illuminates the hydrogen bubbles in the working section.
    Flow visualisation studies can be carried out using plain tap water without the need for additives.
    Optional camera mount allows still camera, video camera or web-cam
    (not supplied) to record the flow patterns.
    The following models, supplied for flow visualization studies, are made of clear polished acrylic and supplied in a protective container:

- One pair 330mm long straight guides
