Strantrol® HRR/pH Controllers

The Strantrol® flowcell and the Strantrol HRR® and pH sensors are an industry standard for disinfection applications where the work value of a disinfectant is to be optimized.

The simple see-through flowcell allows for a visual check of the sensors. The flowcell is designed for flowrates of 1 to 3 gpm and all sample water flow can be returned to the process as the cell can operate under pressure of up to 100 psig. The Strantrol® sensors are well known for their accuracy, speed in response and long life.
