The D400 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. OxyProbe dissolved oxygen sensors carry a 1-year warranty. Also available as D405 with right angled connector.

The OxyProbe D400 (25mm) autoclavable Dissolved Oxygen sensor offers rugged performance for side ports. It does not need a housing as it fits directly into the vessel, therefore reducing risks of contamination.

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
  • Reduced random sensor mobility on flat surfaces (won’t roll off the table)

D400 Dissolved Oxygen Sensor Specification

Features:

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

How to choose a sensor

  1. Confirm the entry site is a standard 25 mm port.
  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 and 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 DO sensors require cable and connector assemblies.

Compatible Cables

The D400 DO Sensor uses a D4 connector. This industry standard connector was the first, and is still, the best choice for DO sensors. We recommend the following cables for use with the D400 Dissolved Oxygen sensor:

Cable Type Sensor connector & Device Connector Device Terminal
D4 plug to Lemo 6
DO Cable D4 to Crimped Ferrules

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.
