0040N-10D

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.
