Weigh your butane or propane ASME solvent tanks with an explosion proof scale to add precision to your extraction SOP. With an explosion proof scale from Butane Extraction Equipment you can know exactly how much butane or propane you are injecting into your material columns and monitor your recovery. Each scale comes with a C1D1 digital display so you can visually monitor your solvent with convenience. These scales come included in any of our "turn key" butane extraction systems.
