Water Control: Automatic pH/ EC regulator

The systems of automatic regulation of HNE-500 Series are designed to offer real solutions and cheap monitoring of the most important parameters of the water. Equipped with two different inputs for pH and ORP or EC, they are used in many different areas, from disinfection in swimming pools, drinking water testing, in the processes of industrial production, as well as in agriculture and the food branch.

Precise and economical controls

  • guaranteed measures HANNA
  • they do not require the use of reagents for the analysis

Easily used

  • Short installation time
  • Simple features, even for not-qualified operators
  • Quick and easy calibration through the front trimmers
  • minimum maintenance
  • Miniregulator with a large LCD

Selecting the type of control:

  • OFF: Relay doesn't dose (display only)
  • AUTO: The relay doses according to the setpoint settings
  • ON: Relay doses continuously

Safe and reliable dosage

  • Overdose indication: it alerts you when the relay remains active for too long, indicating an anomaly
  • A LED indicates the working mode (measurement, dosing or alarm)
