HP-960FTP

Panel-mount type pH meter with 4-point alarm time sharing proportional control

A compact water quality meter that offers a wide range of features and functionality.

A pH meter that supports time-proportional control. Suitable for pH monitoring and control in various production processes, as well as wastewater treatment and other applications. We offer a wide range of cleaning devices to accommodate a variety of samples.

Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

Lineup of a wide range of electrodes

A wide variety of electrodes are offered to match the sample characteristics. The dome-shaped electrode with minimal irregularities provides confidence in its workability and strength when dealing with dirt. Additionally, by having two junctions, clogging can be better avoided, and stable measurement values can be expected (sleeve-type electrodes which allow easy release of inner liquids are also available).

Comprehensive range of cleaning devices

A diverse lineup of cleaning devices is offered. The ultrasonic cleaner can be retrofitted to HP-960FTP sites that are not equipped with a cleaner.

Control operations

ON/OFF control

  • Upper and lower limits setting range: 0.00 pH to 14.00 pH
  • Control width: 0.00 pH to 4.00 pH (±0.00 pH to ±2.00 pH)
    Time-division proportional control
  • Upper and lower limits setting range: 0.00 pH to 14.00 pH
  • Proportional band: 0.00 pH to 4.00 pH
  • Cycle time: 5 s to 300 s
  • Control output shift capability: 0% to 50% of shift volume for the cycle time
  • Self-extending cycle time capability: The cycle time is extended automatically when the deviation value enters a set range (F zone) in proportion to the deviation value (This feature has no effect when the shift function has been enabled).
  • F zone: 1% to 100% of the proportional band (Self-extension of the cycle time starts working when the deviation enters the above range).
  • Upper limit for extending the cycle time: 0 s to 300 s.
  • Maximum control volume: 50% to 100% (To be applied regardless of whether the measured value is in the proportional band or not).
Calibration functionTwo-point automatic calibration or manual calibration.
Two-point automatic calibration: with automatic validation of the electrode characteristics.
  Types of standard solution: pH 2, pH 4, pH 7, pH 9 and pH 10 (JIS)
  Combination of standard solutions: pH 7 and one of the others
  Manual calibration: Freely selectable, but the difference should be over 2 pH.
Temperature calibration (one point).
