Underwater pH Sensors
pH Sensor Caps
The PHCAP represents a new generation of optical pH sensors from PyroScience and a viable alternative to traditional electrochemical sensors. The PHCAP is attached via the PyroScience SUB-connector directly to a compatible read-out device. An additional protective cap makes the PHCAP highly robust against mechanical impact and ideal for long-term monitoring applications. The PHCAP integrates a pH sensor spot and allows measurements between pH 7.0 and 9.0 on pH total scale. It is based on an optical detection principle and therefore does not require a reference electrode, leading to a minimized effect of high ionic strength thus making it to a suitable sensor solution for long-term measurements especially in seawater.

pH Screw Cap Probes
PHROBSC-PK8-SUB
- pH robust screw cap probe
- For pH measurements between pH 7.0-9.0
- Robust fiber with threaded tip
- Exchangeable Sensor Screw Caps
- Minimal cross-sensitivity to high ionic strength
- With underwater SUB-connector (-SUB)
This robust pH screw cap probe represents a new generation of fiber-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. The PHROBSC-PK8-SUB comes initially with 4 sensor caps. If more caps are required, an additional set of 4 pH sensor screw caps (PHSC-PK8) can be obtained.

pH Sensor Spots
PHSP5-PK8T
- pH sensor spots
- For marine measurements on pH total scale
- Measurement range pH 7.0-9.0
- Sensor spots (8 pcs.) 5mm in diameter
- No reference electrode required
- Contamination-free due to non-invasive measurement
PyroScience pH sensor spots allow pH measurements over a defined pH range of 7-9 (on pH total scale) 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.
