    Hydrometers:

    1. Shake product well before using

    2. Rinse Hydrometer with distilled water

    3. Pour Brightwell Refractometer & Hydrometer Calibration Standard fluid carefully into hydrometer to avoid bubbles

    4. Tap hydrometer to dislodge any bubbles and use a stirring rod to tap the swing arm to release any remaining bubbles

    5. Read hydrometer, at 25 deg c ( 77 deg F ) you should read a specific gravity of 1.026
