As one of the first machines developed by SANTINT, the M3 is a workhorse that has an accuracy of 1/384th of a fluid ounce, and it is precise and fast. The M3 comes standard with 2.5L POM canisters with 2 oz pumps but can be upgraded to stainless steel canisters with 2 oz pumps. For locations that do large volumes, we have 3.8L stainless steel canisters with 5 oz pumps.
