Models D140 and D145 OxyProbes

The OxyProbe 12 mm dissolved oxygen sensor offers the most rugged and versatile design for benchtop vessels. The compact profile saves space on a crowded headplate. It will fit directly into any 12 mm multipurpose port with standard compression fittings or Pg13.5 threads. The small diameter facilitates DO measurement in small volumes, especially bottles and spinner flasks.

The OxyProbe 12 mm DO 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)

How to choose a sensor:

(1) Determine how far the sensor should project into the vessel.

(2) Decide whether a right angle connector is preferred over a straight connector.

(3) 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.
