Streaming Current Instruments

The Micrometrix® Streaming Current Instruments represent new advances in coagulant dose control.

The patented sensor design includes XL (extended life) technology with renewable probe and replaceable Teflon® sleeve.

Streaming Current Detectors (i.e. SCM/SCD)  have demonstrated the ability to optimize coagulant dosing and prevent plant upsets.
