The PPB Hygienic can be ordered with ranges of 0-100 ppb or higher, and is also available in a dual-range model. It can be cleaned at 100°C. Its probe is designed to fit into a standard ND40 stainless steel dairy fitting with no difficult-to-clean dead spaces. The probe tip is made from a single piece of high-stability plastic and the membrane fits flush with a special gasket.
The PPB range of instruments are characterized by high accuracy, very fast response time, ease of use and maintenance, reasonable acquisition cost and very low cost of ownership.
The probe does NOT need regular service
