4670

The 4670 comprises a wall-mount instrument together with one of a number of sensors designed to provide a complete solution for all drinking water processing, process water and sewage treatment processes. Ranges are configurable between 0 to 1 NTU and up to 250 NTU and 2,000 FTU. Flow-through and immersion sensors come supplied complete with an auto-cleaning function. simple maintenance and operator safety is ensured using the ABB dry standard calibration method and eliminates the use of toxic formazine.
