MultiGasAnalyser OR-703 is the
perfect extension to FlowAnalyser or CITREX H5 when high precission
concentration measurements of
anaesthetic and respiratory gases are desired.
The RS-232 connector enables respiratory device manufacturers to fully integrate the FlowAnalyser into an automated test system. With ASCII-based commands you can simply upload measured values from the FlowAnalyser to your own service software.
Flexibility plays a pivotal role in mobile applications, and the FlowAnalyser adapter set excels in this aspect. It offers a wide range of adapters, ensuring effortless and accurate connections for your test objects.
Our innovative and cost-effective test lungs safely test ventilators and anesthesia machines for function and precision.
Software for FlowAnalyser and CITREX.
Monitor and save your ventilation parameters of flow, pressure, and volume measurements comfortably on your PC. FlowLab graphically displays your measured values numerically or as real-time curves. Trending reports are generated with up to 100 hours of data to check the long-term functionality of your device. Simplify the verification process of your ventilation equipment by creating your own individual test reports that can be stored electronically or printed.
The FlowLab software is available in 15 languages.

Create test sequences for any medical device that produces pressure or flow such as a ventilator or anesthesia machine. A powerful editor allows you to design your test sequence by inserting components such as text, graphics, images, measured values and more. Very efficiently reproduce a test sequence specified by the medical device manufacturer. Run tests and generate PDF test reports with an electronic signature and your company’s logo. Test sequences can be saved for reuse, sharing, and standardization across your organization.
With a few clicks, measurement values can be saved directly from FlowLab into a report and printed out. Freely definable content allows you to design test reports according to your needs. Thus, in addition to the measured values, all the data of the test object is documented for a clear overview.
The generated control numbers help you keep an overview of your test reports and assign the correct document to the corresponding test object, even after a long time. You can also easily insert your company logo, so that each report can be visually recognized as a company document.
FlowLab helps you automatically create clear documents and saves you the trouble of creating test reports in word processing programs.
For precise analysis of measured values, up to six time-dependent curves can be displayed in FlowLab. The adjustable cursors allow measurement curves of all ventilation parameters to be measured. In the curve trigger settings, you can, among other things, set trigger types or triggering thresholds so that only the desired measuring ranges of the curves are displayed.
To obtain an overview, all curve fields can be color-matched or labeled individually.
With just one click, all curve fields can be saved as an image or printed out.
The trending function of FlowLab allows you to trend measurements for up to 100 hours. It is very easy to select up to 10 measured values and define settings such as recording time, recording rate and time axis. The recorded values can then be exported to an Excel spreadsheet, giving you the possibility to carry out individual evaluations in a calculation program outside of FlowLab.
FlowLab’ s trending capability is the right function when it comes to performing troubleshooting.
In the numeric display in FlowLab, up to 20 measured values can be displayed and sorted simultaneously. In addition, statistical variables such as mean, minimum and maximum values are displayed in real time and can be compared with predetermined set points and tolerances if desired. This makes it easy to see if a certain measured value is within the specified tolerances of the measurement object. Everything at a glance, freely configurable and clearly presented. The optimal display to compare measured values and carry out tests quickly.
The FlowAnalyser PF-301 VAC and PF-302 LOW devices are options for specific testing requirements.
The PF-301 VAC measures pressures up to ±1000mbar, enabling vacuum and flow measurements with a dedicated connector.
The FlowAnalyser PF-302 LOW is designed for precise low-pressure measurements, measuring from 0 to 5 mbar with extended accuracy using a dedicated pressure connector.
Both versions offer the same extensive functions as the Flow Analyzer PF-300.
The PF-300 measures the highest accuracy, with less than 1.75% deviation in readings for two channels: 0 to 20 and 0 to 300 L/min.
The PF-300 pressure sensors measure low, high, differential, vacuum, and barometric pressure. It offers many parameters for testing any respiratory device, including high-frequency oscillation stroke rates up to 16.66 Hz.
With the powerful FlowLab software for your PC, you can experience real-time monitoring of flow, pressure, and volume parameters through visual curves.
Automate test sequences to enhance device efficiency and save valuable testing time. Generate personalized test reports in PDF format and record parameters for over 100 hours for in-depth analysis and documentation.
The PF-300 can measure gas flow in 10 different gas types. Seventeen supported gas standards enable testing on a wide range of medical devices.
The FlowAnalyser offers remote control via RS-232 and USB interfaces and an "External Trigger" input for precise control and synchronization, enabling streamlined testing and data transfer.
Upgrade your FlowAnalyser PRO easily to an anesthesia ventilator tester with the optional MultiGasAnalyzer OR-703 featuring Masimo® Technology. This expansion lets you measure CO₂, N₂O, and all volatile anesthesia gases using the most compact mainstream gas sensor available.
You can view, store, and track all parameters directly on the PF-300 and the FlowLab software. The MultiGasAnalyzer OR-703 is compatible with your existing FlowAnalyser PRO and CITREX H5 fleet.
Annual calibration of your FlowAnalyser is crucial to ensure precise measurements. Take advantage of our hassle-free EasyCal calibration service to arrange pick-up, generate shipment and customs papers online, and preserve the accuracy of your gas flow and pressure measuring device.
EasyCal provides annual maintenance, software updates, and sensor adjustments to guarantee long-term precision. It is the easiest and most reliable way to keep your device in top condition.
FlowAnalyser PF-300 test sets come with comprehensive accessories suitable for calibrating and verifying all mechanical ventilators and anesthesia machines.
