Oxygen probe DP-PSt3

optical

The oxygen dipping probe type PSt3 for measurement in normal oxygen range consists of a polymer optical fiber where one end is coated with an oxygen-sensitive foil. The end of the fiber is covered in a high grade steel tube to protect both the sensor material and the fiber. The steel tube has an outer diameter of 4 mm and a length of 10 cm. Other lengths are available on request. Due to the use of a polymer optical fiber this probe is compatible to temperatures up to + 70 °C. Excellent long-term stability Pressure resistant (max. 5 bar) Polarization-free No membrane cleaning and replacement necessary No electrolyte solution to replenish Long shelf life
