pH Sensor Spots

PHSP5-PK8

  • Measurement range pH 7.0-9.0
  • For measurements in closed containers
  • No reference electrode required
  • Contamination-free due to non-invasive measurement

pH sensor spots allow pH measurements over a defined pH range of 7-9 in closed sample containers with contactless read-out through a transparent window (glass, acryl glass), with special adapters and optical fibers for fiber-optic meters from PyroScience. This enables incubations in closed systems, preventing potential contamination and simplifying pH monitoring without sampling, also in combination with oxygen and temperature sensor spots.

pH range 7.0-9.0 This sensor is specified for the pH range 7.0-9.0. For detailed specifications, see the respective pdf file in the Downloads tab.

Optical isolation. This sensor type is equipped with an additional optical isolation protection layer. This layer avoids interferences with the measurements in applications at high ambient light (e.g. direct sunlight, illuminated samples) and in fluorescing / light-sensitive samples.

Easy calibration. Calibration of the pH sensors is performed at pH 2 and pH 11 using our easy-to-use calibration capsules (PHCAL2 and PHCAL11). For detailed calibration recommendations, please refer to the manual in the downloads tab.

Standard stock item. This item is typically in stock and small numbers can be shipped quickly. This does not apply for larger amounts, which ship with standard delivery time.
