Model D600 OxyProbe DO Sensor


After several years of refinement we are introducing our latest set of improvements all bundled up in one

new sensor, the OxyProbe? II.

The new membrane design is modeled after our successful 25 mm membrane cartridge. It has an

expandable inner Silicone bladder that holds the electrolyte within a 316L stainless steel cage. During SIP

processes or during auto claving the electrolyte turns to steam, but does not distend the measurement

membrane because the internal bladder expands first, taking the pressure off the sensitive measurement area. This allows us to have a maximum of electrolyte present, with minimum risk of damage to the sensor. The new membrane cartridge design is easy to use and durable enough to be used many times over if necessary.

Model D630 OxyProbe DO Sensors
The ports of Sartorius fermentation vessels are longer and have a slightly different internal design. In order to seal properly, the o-ring on these sensors has been moved closer to the tip of the sensor.

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.

The sensor fits directly into the vessel, eliminating the need for a housing, reducing contamination risks. Few accessories are required. The modular design allows quick replacement of any part, making it easy to maintain and repair the sensor. 


SPECIFICATIONS

Features:
• 316L Stainless Steel
• Serialized for traceability
• RA32 finish with electropolish on wetted parts
• External EPDM o-ring
• Secured retainer ring

How to choose a sensor:

(1) Confirm the vessel has a 25 mm Sartorius side port. Click here for more information.
(2) Determine how far the sensor should extend into the vessel. For most process media, the minimum length is optimal. However, if the media is viscous or tends to coat the inner wall of the vessel, a longer length may provide better performance.
(3) Decide whether a right angle connector is preferred over a straight connector.
(4) Choose cable length and connector. All D.O. sensors require a separate cable connector assembly.

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

OxyProbe ? Dissolved Oxygen Sensors for Standard 25 mm Ports

Model D400 and D405​ OxyProbe DO Sensors

The OxyProbe dissolved oxygen sensor offers the most rugged design for 25 mm side ports. It fits directly into the vessel, eliminating the need for a housing, reducing contamination risks. The modular design allows quick replacement of any part, making it easy to maintain and repair the sensor. 

All Broadley-James dissolved oxygen sensors are available with optional right angle connector. This low profile design provides:

• Protection against cable fatigue
• Improved grip for sensor extraction
• Increased clearance between vessels

SPECIFICATIONS

Features:
• 316L Stainless Steel
• Serialized for traceability
• RA32 finish with electropolish on wetted parts
• Internal and external silicone o-rings
• Secured retainer ring
