For epoxy batches smaller than one Mini Pump stroke, the 320 scale accurately measures the correct ratio of resin and hardener from 4.4 fl oz down to just a few drops of mixed product. The scale can also be used to confirm the accuracy of your WEST SYSTEM dispensing pumps and to consistently add pigments or other additives. The scale comes in a convenient kit for small projects. The kit includes dispensing bottles, 3.25 oz and 1 oz plastic mixing cups, mixing sticks and pipe cleaners.
