pH Minisensor

PHF500-PK6.5

  • Measurement range pH 5.5 - 7.5
  • Fixed in a needle, tip protruding 5mm
  • Tip diameter 500µm
  • for fast pH measurements (t90 at 25°C < 10 sec)
  • Without optical isolation

The pH minisensor PHF500-PK6.5 is composed of a black fiber-optic cable, ca. 2m in length with ST-plug for connection to the optical meter FireSting®-PRO. The pH sensing tip is located at the very end of the optical fiber and is fixed in a needle. The fragile 500µm sensor tip protrudes (5mm) unprotected from the needle and has to be protected from light and mechanical stress. Available for a defined pH range of pH 5.5-7.5, each packaging unit contains 2 pH minisensors. Perfectly suited for pH measurements in small volumes and for fast pH measurements.
