The product DIP or Dosing Instrumentation Pool is made for swimming pool applications but is used today in water treatment applications as well. It measures up to three parameters and can control two parameters at the same time thus providing perfect control of the water quality. The DIP speaks five languages making it easy for those users without previous knowledge to carry out all of the operations. Other features are maintenance-free measuring electrodes, a sample-water sensor to prevent overdosing, a choice of control functions, display languages such as english, German, French, Polish and Russian, menu-driven operator prompting and fast calibration
