MicroTrac

The MicroTrac is a microprocessor based feed and bleed toroidal conductivity controller designed to control conductivity and feed inhibitor in cooling tower systems. Featuring innovative toroidal sensor technology, the MicroTrac provides an economical control platform that is not susceptible to sensor fouling and never requires calibration! The MicroTrac conductivity controller has a 0 - 9,999 µS/cm range, making it ideal for other applications as well, such as rinse, industrial process, wastewater, etc.
