The main features of the HI 720 controller series include:

• Measurement and control of conductivity or concentration
• Concentration can be measured as usual TDS (fixed ratio) or through custom conductivity/temperature/concentration curves
• Customizing temperature coefficient table and NaCl temperature compensation according to IEC 746-3, in addition to the standard linear compensation
• Auto-ranging
• Display reading offset adjustment for temperature
• Temperature level alarm
• Cleaning in place activated through two cleaning commands, or triggered by a variety of events
• Hold management, including a digital input to enter the hold mode through an external trigger
• Conductivity probe check
• Digital transmitter input
• Pt100 or Pt1000 temperature sensor with automatic recognition and damage test
• Calibration time-out
• Logging of the last 100 error, configuration and cleaning events
• Alarm fault current (3.6 mA or 22 mA)
• SMS messages sending
• Alarm configuration can be customized: different errors can lead different actions (alarm relay activation, fault current, hold mode, automatic cleaning, SMS message)
• RS485 communication with additional capabilities, such as error log file downloading and cleaning commands
• Daily programmable control timing
• Diagnostic features
• Password protection
