Product Name:Oxygen Dipping Probe
Product Type:Dissolved Oxygen Meter
Product Model:DP-PSt3
Applications:Water Quality Analysis,Biopharmaceutical,Cosmetic Testing,Biochemistry/Molecular Biology,Life Sciences,Bio-Pharmaceutical Vaccine Industry

The Oxygen Dipping Probe consists of a polymer optical fiber with a polished distal tip which is coated with a planar oxygen-sensitive foil.

The end of the polymer optical fiber is covered with a highgrade steel tube to protect both the sensor material and the optical fiber. The steel tube has an outer diameter of 4 mm and a length of 10 cm. The diameter of the fiber itself is 2 mm.

The standard fiber cable length is 2.5 m; the outer diameter of the cable is 2.8 mm. If a cable length of more than 2.5 m (maximum 15 m) is required, please contact
our service team.
