D605-VP (25mm) OxyProbe II Dissolved Oxygen 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 D605-VP Oxyprobe II Dissolved Oxygen Sensor has a right-angled variopin connector. It is also available as the D600-VP with straight connector and in both formats with D9 connectors.

The new membrane design is modelled after our successful 25mm membrane cartridge. It has an expandable inner Silicone bladder that holds the electrolyte within a 316L stainless steel cage. During SIP processes or during autoclaving 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.

The D605-VP (25mm) Oxyprobe II Dissolved Oxygen Sensor offers the exact same functionality as the D605 but instead of our standard straight D9 connector it has a waterproof right-angled VarioPin connector for VarioPin assemblies. It is also available with a straight VarioPin connector.

The D605-VP features a right-angled connector rather than the straight connector seen in the D600-VP OxyProbe II. 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)

Hygienic Sensor Design

  • Microrganisms cannot adhere to the sensor surface due to the enhanced finish (N5/Ra15µ in Quality).
  • The sensor is fully sterilizable and autoclavable.

Time-Saving Maintenance

  • Membrane body and sensor inner body can be changed out very quickly. A simple membrane body replacement takes just two minutes and can be made on site by the user.
  • Due to the modular design, the different sensors have basically the same spare parts. This minimises inventory stocking requirements.

D605-VP (25mm) Oxyprobe II Dissolved Oxygen Sensor Features Overview

  • Autoclavable and steam sterilizable
  • Accurate measurement and quick response.
  • Long lasting and easy to maintain membranes.
  • FDA positive listed materials of construction.
  • Hygienically polished N5 surface finish (Max. Ra15µ in).

Compatible Cables

The D605-VP OxyProbe II DO Sensor uses a VP (VarioPin) connector. This multifunctional electrode is capable of both receiving and processing a number of signals at the same time. We recommend the following cables for use with the D605-VP OxyProbe II Dissolved Oxygen sensor:

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 or a straight connector.
  4. Choose cable length and connector. All DO sensors require cable and connector assemblies.

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.
