The D25RE10 water-driven proportional dispenser with a 1:33 to 1:10 adjustable ratio is five inches smaller than previous Dosatron units and includes improved external adjustment capabilities as well as a five-stage mixing chamber. The company says a check valve assembly helps reduce blockages. An optional bypass switch is available.
