compact O2/CO2 analyzer

BlueInOne Ferm

Combined CO2/O2 analyzer for Real time monitoring of bioprocesses

Technical Short Facts

  • Concentration ranges: CO2: 0 - 10 Vol.%, O2: 0.1 - 25 Vol.% , CO2: 0 - 25 Vol.%, O2: 0.1 - 25 Vol.%, CO2: 0 - 10 Vol.%, O2: 1 - 50 Vol.%, CO2: 0 - 25 Vol.%, O2: 1 - 50 Vol.%
  • Measuring principle: infrared (IR) CO2 sensor, ZrO2 (O2 sensor)
  • Temperature inside of the sensor unit: 580°C/1076°F (O2 sensor unit)
  • Various opportunities for mechanical connection (eg 4, 6, 8, 10, 12mm outer diameter, 4,6,8mm inner diameter, ¼”, 1/8” , 1 ¼”, ¼” and ½” swagelok, TriClamp)
  • Electronic output: Active output, maximum 500 Ohm at 24V power supply, RS232, RS485 Modbus, 2x 4-20mA, USB, Modbus OPC server (with BlueVis)
  • Optional display available

Using BlueInOne Ferm oxygen and carbon dioxide concentrations in your bioprocess can be monitored online and in real-time. Sitting in the exhaust gas flow behind the sterile barrier, the device can be calibrated at any time without causing potential contamination issues. Sampling systems, valves or pumps are unnecessary. Fluctuations of pressure and humidity are automatically compensated. Thus readings are both extremely accurate and precise. BlueInOne fits on every fermenter from benchtop to industrial scale.

BlueInOne Ferm – robust and precise gas analysis to help you understand your process

  • different CO2 and O2 ranges available
  • Compact stainless steel housing ➔ robust and easy to clean
  • PAT and QbD conform in-situ-measurement ➔ for highest standard of quality
  • Auto compensated humidity and pressure ➔ no need for extra gas coolers, pumps or valves ➔ highest fail safety
  • Real time process optimization ➔ see what happens when it happens – fast response options

Application areas

  • Bioprocesses in general
  • Online fermentation monitoring
  • From lab to industrial scale

Keep an eye on your data

For all BlueInOne gas analyzers there is a convenient additional display available. Measured data is shown in real-time. The display is connected via data cable (up to 5 meters long) to the analogue 4-20mA output of the BlueInOne analyzer without blocking any ports. Magnets on the rear of the housing of the display make mounting easy and convenient. In addition, the display includes a button for performance of the 1-point calibration.

  • Convenient: the current measured values directly on site in view
  • Easy installation: quick control without software
  • Flexible to install, easy mounting
  • Time savings: start the one-point calibration easily even if the BlueInOne is hard to reach
  • 4-20 mA port included, no ports are blocked
  • Variants for all BlueInOne available

BlueVary – for 100% flexibility

BlueVary is a maintenance free gas analyzer for variable applications. By freely selectable sensor cartridges different measuring tasks can be covered by just one device.

BlueVary consists of a basis element with measurement places for two of the variable gas sensor cartridges. That way two gases can be measured in parallel. The third place holds a sensor cartridge for pressure and/or humidity. An integrated display ensures insight of the measured data at any time. Various mechanical connections make BlueVary fit on every fermenter. Numerous data output possibilities are available. Annual maintenance is unnecessary. To maintain accuracy of the readings a one-point calibration has to be performed (by the user) in reasonable time intervals.
