The OxyProbe 12 mm autoclavable Dissolved Oxygen sensor has the same rugged performance as the 19 mm and 25 mm sensors. This polarographic sensor utilizes the longer silver anode and small cathode which has become the industry standard. It also uses the same semi-permeable, Silicon/Teflon composite membrane, reinforced with stainless steel mesh.

All OxyProbe dissolved oxygen sensors are available with a right angle connector. This low profile design provides:

Protection against cable fatigue
Improved grip for sensor extraction
Increased clearance between vessels
Reduced random sensor mobility on flat surfaces (won’t roll off the table)

Specification

316L Stainless Steel
Serialized for traceability
RA32 finish with electropolish on wetted parts
Internal EPDM o-rings

The internal seals of an Oxyprobe are all mechanical seals using o-rings. There are no adhesives to leak or fail in process, making this a more rugged and reliable sensor. Replacing the cathode is also much easier and faster since there is no sealant to clean from the threads. No sealant also makes the job of replacing the cathode much faster and cleaner.

How to choose a sensor

Determine how far the sensor should project into the vessel.
Decide whether a right angle connector is preferred over a straight connector.
Choose the correct cable length and connector. All DO sensors require cable and connector assemblies.

It is important to regularly maintain the sensors by inspecting and calibrating them. The membrane cartridge should be checked and refilled prior to every use.
