Industrial Application
The HI991301 is specifically optimized for high-range conductivity environments such as cooling tower water treatment, boiler feed water monitoring, and industrial wastewater effluent discharge. In cooling tower applications, maintaining precise EC and TDS levels is critical to preventing scaling and corrosion. The high-range EC capacity (up to 20.00 mS/cm) allows operators to accurately monitor concentration cycles and automate blowdown processes. The IP67 waterproof plastic housing ensures operational reliability in high-humidity, splash-prone industrial zones.
