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 range 7.0-9.0 This sensor is specified for pHT (pH total scale) in the marine pH range of 7-9. 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.
SUB-connector (-SUB). Underwater sensor connector (instead of standard ST-connector) needed for applications with underwater devices.
