0040-10D ISFET pH electrode

ISFET pH electrode

The Ion Sensitive Field Effect Transistor (ISFET) pH electrode has a semiconductor based sensor located less than 100 µm from the flat surface of the tip.

Segment: Scientific
Division: Water Quality
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.
  • pH measurement can be perfomed on a single drop of liquid sample or moist surface of solid or semi-solid sample.
  • Semiconductor based sensor eliminates concern that the electrode will get damaged. It will not crack or break like conventional glass electrodes.
  • Can be stored dry
  • Waterproof
  • Replaceable sensor (Model 0141N)
  • The diagonal cut structure helps to prevent bubbles from forming on the electrode tip. Reliable calibration and measurement in beakers.

 

Applications:

  • Environments where glass material cannot be used.
  • pH measurement of gelatinous materials in shallow containers (e.g., nutrient agar in petri dishes)
  • Surface measurement of skin, meat, cloth and paper.
  • If solid or semi-solid sample has minute amount of moisture, wet the surface with pure water prior to measurement.
  • Clean with neutral detergent and warm water after measuring oily samples.
