Maintenance Tips: 

Falling Sand Tester

• Prior to testing, ensure a suitable container is placed under the receptacle to collect the abradant.
• Do not store abrading material in the sand container / funnel.  The abradant should be stored in a sealed container to prevent possible contamination.
• It is important to note, although sand may meet the sieve requirements the abrading qualities may differ.  For reproducible results, sand should be used from the same source and have the same mineral properties and shape.
