pH meter 9794 model

The 9794 model pH meter is a measuring instrument designed for measuring the pH of solutions used in boiler plants and pure water manufacturing systems on-line.


  • Compact and lightweight (DIN96 size).
  • Provided with a wide variety of standard liquids for calibration.
  • Equipped with five types of temperature compensation functions for solutions.
  • Capable of calibrating the standard liquid accurately without individual variability with a built-in electrode output stability discrimination function.
  • Allowing for arbitrarily setting the transport output span of 2 pH or higher by 0.1 pH.
  • Capable of determining the quality of electrode characteristics.
  • Equipped with temperature compensation functions for solutions.
  • When the meter is put in maintenance mode, ST-BY in the liquid crystal lights up and the transport output holds the value immediately before switching. Since the adjustment output contact is turned off, unneeded alarms will not be set off.
  • Capable of arbitrary settings within the measurement range with an upper and lower limit adjustment contact.
