Dual-Channel Universal Process Controller For Industrial Applications – HI520

HI520 is an advanced process controller that can be configured for applications requiring monitoring and/or control of four main water-analysis parameters: pH, ORP, Conductivity, and Dissolved Oxygen.

  • Waterproof IP65 (Nema 4X) enclosure
  • Multi-color LED status indicators & audible alarm
  • Universal mounting kits available with wall, pipe, and panel mounting options
    (All mounting kits must be ordered separately.)

This product is currently out of stock and unavailable.

HI520 is Hanna’s first dual-input process controller that accepts virtually any combination of compatible probes. Designed to adapt to unique process control requirements, users have the option to enable or disable each channel independently.

Additionally, HI520 introduces enhanced industrial control by operating a control-loop system whereby users have the option to run channel control either independently or configure to be triggered sequentially upon reaching the other channel’s set point(s) (1, 2, or both). The device operates a logical channel with built-in mathematical functions. This function is intended for when the controller works as an analyzer for monitoring high/low parameter levels between two identical inputs with identical measuring configurations.
