After several years of refinement we are introducing our latest set of improvements all bundled up in one new sensor, the OxyProbe® II. The D540-VP has a straight VarioPin connector.

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 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 D540-VP (12mm) Oxyprobe II Dissolved Oxygen Sensor offers the exact same functionality as the D540 but instead of our standard straight D9 connector it has a waterproof straight VarioPin connector for VarioPin assemblies. It is also available with a right-angled VarioPin connector.

Hygienic Sensor Design

  • Micro-organisms 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 minimizes inventory stocking requirements.

D540-VP (12mm) 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).
  • Wetted O-rings comply with FDA and USP Class VI standards.

Other Highlights

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!

How to choose a sensor

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.

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.
