Probe with Stainless Steel Housing for Online pH Monitoring pH Dipping Probe DP-HP5 The pH dipping probe DP-HP5 consists of a polymer optical fiber where one end is coated with a pH sensitive foil. It is covered with a high grade steel tube to protect the fiber and the sensor material. The steel tube has an outer diameter of 4 mm and a length of 10 cm. Other lengths are available on request. Due to its slender shape the probe can be used for profiling applications in coarse sediments. As this probe is based on a polymer optical fiber it is compatible with temperatures up to + 50 °C.
