SST-HP5-US

pH Sensor Stick SST-HP5-US (Minimum Order Quantity: 3)

  • Non-invasive pH measurements in a range of pH 5.5 - 8.5
  • Small size
  • Easy connection via Luer Lock
  • For customized integration & pefusion cell culture monitoring

This Luer Lock adapter is equipped with a miniaturized pH Sensor Spot type HP5 (measurement range pH 5.5 - 8.5). A polymer optical fiber is attached to the Sensor Stick and connects it to a pH meter. This way continuous, non-invasive pH measurements can be performed. The pH Sensor Stick can easily be integrated in customer specific flow-through cells or experimental set-ups via Luer connectors. The SST-HP5-US is independent of flow velocity or electromagnetic fields and due to its small size it can be implemented in many set-ups where other pH measurement equipment simply does not fit.

Specification

SST: sensor stick
HP5: pH sensitive coating
US: not irradiated
