Product Description

The Hanna HI943500 Conductivity Analog Controller is a precision instrument designed for continuous monitoring and control of conductivity in industrial, water treatment, or laboratory applications. Panel mounted and compatible with potentiometric conductivity probes (HI7638), it supports direct probe connections with cable lengths up to 20 m, eliminating the need for an external transmitter.

This model provides exceptional measurement flexibility through four selectable measurement range options, catering to a wide range of process requirements: HI943500A (0.0 to 199.9 mS/cm), HI943500B (0.00 to 19.99 mS/cm), HI943500C (0 to 1999 µS/cm), and HI943500D (0.0 to 199.9 µS/cm). With a manual, two-point calibration using offset and slope trimmers, users achieve a high accuracy rating of ±2% F.S.

  • Direct potentiometric probe connection ensures accurate and responsive conductivity readings for industrial processes.
  • 4-20 mA isolated analog output enables seamless integration with recording devices, PLCs, or remote monitoring systems.
  • Automatic temperature compensation between 0 to 60°C (32 to 140°F) supports robust measurements across dynamic environments.
  • Enclosure crafted from flame-retardant ABS ensuring durability, featuring a transparent splash-proof front cover for panel protection.
  • Large LCD display with backlighting and a membrane keypad allows for straightforward operation and diagnostics.
  • DIN panel cutout dimension: 141 x 69 mm; user-selectable power supply: 115 or 230 VAC ±10%, 50/60 Hz.
  • Manual two-point EC calibration provides operational flexibility and precision for process control.
  • Suitable for industrial, laboratory, and water treatment facilities.

The instrument is engineered with an array of auto-diagnostic functionalities and is ideal for precision conductivity control in process industries, including water/wastewater treatment, manufacturing, pharmaceutical, food & beverage plants, and environmental monitoring. Weight is approximately 1 kg, making it suitable for compact panel installations.
