D605-VP (25mm) OxyProbe II Dissolved Oxygen Sensor

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 sterilisable 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 sterilisable
• 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).
• Wetted O-rings comply with FDA and USP Class VI standards.

Other Highlights

• Comes with either waterproof VarioPin or D9 connector.
• T-Pull connector versions allow for easy removal from fermenter and reduces strain on cable.
• Straight connector version D600-VP also available.
• Variety of sensor lengths available.

Replaceable Anode/Cathode Assembly

A concept pioneered by Broadley-James, this unique assembly permits the sensor to be repaired quickly and reliably. Send your sensors to us for rebuild and save about half the price of purchasing a complete new sensor assembly!

Specification

• 316L Stainless Steel
• Serialised 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 or a straight connector.
4. Choose cable length and connector. All DO sensors require cable and connector assemblies.

Membrane Kits

Broadley-James offer a range of membrane kits to suit all our dissolved oxygen sensors. These include everything required to replace the membrane cartridge and internal o-rings. All kits include:

• QC Certificate
• Material Cert

The following membrane kits are suitable for use with the D605-VP (25mm) OxyProbe II DO Sensor:

Membrane Kit	Example Image	Kit Contents
Single Cartridge Kit for OxyProbe II Part No. MK29-01		One 25 ml bottle of electrolyte One membrane cartridge One set of internal o-rings
Four Cartridge Kit for OxyProbe II Part No. MK29-04		One 25 ml bottle of electrolyte Four membrane cartridges Four sets of internal o-rings
16 Piece Cartridge Kit for OxyProbe II Part No. MS29-16		16 membrane cartridges in one easy-to-store box. Internal o-rings and electrolyte must be ordered separately.

OxyProbe II Replacement Cap sleeve

Replacement cap sleeves are available for OxyProbe II Sensors in both standard (Part No. AM-9657-S) and guarded (Part No. AM-9657-G) formats.

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:

Cable Type	Sensor Connector & Device Connector	Device Terminal
VP plug to 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.
