Oxygen probe DP-PSt6

optical

The oxygen probe DP-PSt6 for measurement in trace oxygen range basically consists of a polymer optical fiber with an oxygen-sensitive sensor foil attached to one end. It has a measurement range of 0 - 5 % oxygen with a detection limit of 1 ppb. This 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. Measurement range of 0 - 5 % O2 with 1 ppb detection limit Excellent long-term stability Pressure resistant (max. 5 bar) Polarization-free No membrane clenaing and replacement necessary No electrolyte solution to replenish Long shelf life
