Double headed doser with independent control for each side. Two different products can be dosed at completely different ratios.
Key Features
This unique dosing system allows two products to be dosed at the same time at completely different dosing ratios.
Only one flow sensor needs to be fitted.
This doser can also be used to double the pumped output of a Select-640 single headed pump. BUT, remember, if you are dosing 1:500 overall from the Select-648, each side has to be set at 1:1,000. It's just the way the arithmetic works.
