Testing Procedure:

• Draw off a test sample of liquid into your hydrometer test jar
• Gently lower the hydrometer into the liquid until it floats freely
• Spin the hydrometer to eliminate false readings caused by air bubbles clinging to the side
• Take a reading when the hydrometer stops moving, and is not in contact with the side or bottom
• The number read at the top of the liquid is the density (gravity)
