pH Sensors

Robust pH Screw Cap Probe
These robust pH screw cap probes represents a new generation of fibre-based pH sensors from PyroScience and a viable alternative to traditional pH electrodes. This new sensor format is composed of a robust cap adapter fiber with stainless-steel tip (10cm length, ø4mm) and a disposable plastic screw cap with integrated pH sensor. The pH sensor cap can be screwed on the threaded tip of the robust fiber. If worn out, keep the fiber and simply exchange the pH sensor cap and continue with your pH measurements.

pH Sensor Spots
PyroScience pH sensor spots allow pH measurements over a defined pH range of 6-8 in closed sample containers with contactless read-out through a transparent window (glass, acryl glass), with special adapters and optical fibres for fibre-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 Mini Sensors
These pH minisensors are composed of a black fibre-optic cable, ca. 2m in length with ST-plug for connection to the PyroScience optical meter FireSting-PRO. The pH sensing tip is located at the very end of the optical fibre 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 or 7-9 each packaging unit contains 2 pH minisensors. Perfectly suited for pH measurements in small volumes and for fast pH measurements.

pH Sensor Vials
Based on the contactless sensor technology, PyroScience ready assembled vials have integrated sensor stripes for all supported analytes. The glass respiration vials have screw caps with a septum, and are available with ca. 20mL (uncalibrated) volume. Adapter rings allow an easy fixation of optical fibers for read-out with optical meters from PyroScience for incubations in closed vials. The elongated shape of the sensor spots allows also measurements at different heights within the vial using several fibers/adapter rings in parallel.
