Sanitary Conductivity Meter (Wide-range type) HE-960HI

HE-960HI Sanitary Conductivity Meter (Wide-range type)

The HE-960HI is a wide-range type sanitary electric conductivity meter that can measure over a wide range from manufacturing water up to 500 mS/cm, and enables advanced concentration management through abundant outputs. Cleaning-in-Place (CIP) terminal management and a reduction in cleaning solutions is also achieved through accurate surface detection.
And we have developed a lineup of electric conductivity sensors that can be used in conjunction, from the conventional insertion type to the flow-through type with improved cleaning and sanitary properties.

  • Simultaneous 4-channel output
    Advanced concentration management is possible through simultaneous 3-channel output of low, middle, and high concentrations, etc.
  • Five contact alarms
  • Input signal can apply for analog output range selection
  • Including nitric acid, phosphoric acid, sodium hydroxide, and 2 user-specified types, the concentration of a total of 5 types of chemical solutions can be output
  • Built-in Communications Function (RS-485)
    HE-960HI is equipped with an RS-485 interface to allow you to check measurements and check / change the set points from a remote location.
