MiniTrode pH Sensor Details

The MiniTrode pH Sensor is expertly designed for precise pH measurements in very small volumes. This combination pH electrode combines a pH glass membrane and reference into one compact tool. As it features a slender 3 mm shaft diameter and 7 mm immersion depth, it provides accurate readings in limited sample sizes, making it a popular pH sensor choice for applications involving vials, tubes, and even microplates. 

The electrode operates effectively across a pH range of 0 to 14 and a temperature range of 0°C to 100°C, ensuring versatility in various laboratory settings. Equipped with a Hamilton Everef reference system and an S7 connector head, the MiniTrode ensures stable and reliable measurements, facilitating seamless integration and long-term benefits for any laboratory measuring pH in small volumes.

Precise and accurate small-volume pH measurements.

Excellent stability and longevity for research and quality control applications.

Minimize disruptive downtime with simple cleaning and low maintenance.

Microvolume-Ready Design

  • 60 mm a-length with 3 mm shaft diameter.
  • Immersion depth of only 7 mm.
  • Engineered for pH measurements in microplates, small tubes, and vials.
     

Long Life and Exceptional Performance

  • Durable glass body and ceramic junction are chemically insensitive.
  • Protelyte electrolyte solution prevents diaphragm clogging.
  • Everef reference system minimizes pH drift.
     
  • 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.

  • We particularly appreciated the professional and personable approach.

    The training on pH sensors was highly beneficial for us. After a detailed introduction to the fundamentals of pH measurement, electrode measurement principles, and the topic of troubleshooting/prevention, we had sufficient time to ask our specific questions. This enabled us to apply what we learned immediately and integrate it directly into our laboratory routine. We particularly appreciated the professional and personable approach of Mrs. Näf-Rüdiger, who guided us through the informative and application-oriented training session.
