Product Description

Hanna HI943500C Conductivity Analog Controller is engineered for ultimate process control reliability in laboratory, industrial, and water treatment environments. This panel-mounted controller accepts a direct signal from a potentiometric conductivity probe (HI7638) with cable runs up to 20 m, removing the need for external signal amplification. It is ideal for continuous monitoring and control of conductivity in industrial water, wastewater, boiler feed, process streams, and laboratory applications where precision is paramount.

  • The HI943500C model features a measurement range of 0 to 1999 µS/cm, a 4–20 mA isolated analog output for recorder or PLC integration, and an easy-to-read LCD display with backlighting.
  • Manual two-point calibration is performed through offset and slope trimmers, ensuring measurement accuracy of ±2% F.S., supported by a robust ABS flame-retardant enclosure and splash-proof transparent cover.
  • Automatic temperature compensation between 0 to 60°C (32 to 140°F) guarantees stable readings in changing environmental conditions.
  • Standard panel cutout dimensions are 141 x 69 mm, making it easy to install in control panels.
  • Designed for reliability in demanding environments, the controller is suitable for process, laboratory, water treatment, and manufacturing control tasks.

This instrument is widely used across water treatment plants, laboratories, and industrial process control sectors requiring continuous, accurate conductivity monitoring.
