FlaTrode Details

The FlaTrode pH Electrode is designed for precise flat surface pH measurements, making it ideal for laboratory applications such as testing paper, agar plates, or other truly flat samples. It features a chemically resistant glass body shielded by a shatter-proof plastic shaft. 

This pH probe also includes a Single Pore ring diaphragm to enhance contact between the sample and reference while further resisting corrosion and preventing clogs. This serialized pH probe operates across the full pH range of 0 to 14 with a temperature range of 0 to 60 °C. The Hamilton Everef reference system ensures long-term stability, and the electrode connects via an S7 connector head.

Repeatable, precise pH surface measurements in flat samples

Rapid response time from enhanced contact between sample and reference

Long, reliable pH sensor performance supported by durable materials

Specialty Flat Surface pH Measurements

  • True flat membrane with 1 mm immersion depth ensures full sample contact.
  • Single Pore ring diaphragm enhances contact between flat sample and reference electrode.

Durable pH Electrode Construction

  • Glass body is chemically resistant and easy to clean.
  • Plastic SAN sheath protects the glass body from physical damage.
  • Everef reference system and Polisolve polymer reference support long pH electrode life.

  • Hamilton pH sensors are characterized by their high measuring accuracy and long service life.

    Hamilton pH sensors are characterized by their high measuring accuracy and long service life. This contributes significantly to the control of our processes. They also help us to guarantee the required product quality and to further optimize processes.
