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 PRO measures bi-directional and ultra-low flows with the highest precision. It is suitable for testing low-flow anesthesia devices, capnometers, pneumatic valves, oxygen flow meters, and other applications.
The FlowAnalyser PRO also includes pressure sensors for measuring low, high, differential, vacuum, and barometric pressure, consolidating the capabilities of the entire PF-30x range.
It can measure respiratory parameters for infant, pediatric, adult, and high-frequency ventilators, such as oxygen concentration, gas temperature, and humidity.
Moreover, the FlowAnalyser PRO has ventilator testing apps designed to simplify and expedite your testing procedures.
With their unique automatic breath detection, these apps can detect in- and expiratory breath phases for various respiratory devices, including BiPAP and high-frequency ventilators, making the PRO a unique and valuable testing device.
The FlowAnalyser PRO has a customisable, high-resolution, multi-touch user interface that adapts to your needs.
Direct-access keys let you quickly see the measured parameters for each port.
When you select a key, you can easily view the parameter and its limits, making the operation of the FlowAnalyser PRO intuitive and effortless.
Our ventilator testing apps are designed to streamline and expedite your testing processes and save you valuable time.
The FlowAnalyser PRO offers efficient and automated apps that reduce potential transmission errors, ensuring that your time is used effectively, and your testing is accurate.
The PRO measures the highest accuracy in the market, with less than 1.65% deviation in flow and ULF channel readings. Its pressure sensors measure low, high, differential, vacuum, and barometric pressure.
That makes it your perfect match, especially for testing low-flow anesthesia devices, side-stream capnometers, pneumatic valves, rinse flows, oxygen flow meters, and more. It offers many parameters for testing any respiratory device, including high-frequency oscillation stroke rates up to 33.33 Hz.
The FlowAnalyser PRO can measure breath-based respiratory parameters and automatically detect breath in- and expiratory breath phases for various respiratory devices, including BiPAP machines and high-frequency oscillation ventilators — precise detection up to breath rates of more than 33 Hz.
Upgrade your FlowAnalyser PRO easily to an anesthesia ventilator tester with the optional MultiGasAnalyser 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 PRO and the FlowLab software. The MultiGasAnalyser OR-703 is compatible with your existing FlowAnalyser PF-300 and CITREX H5 fleet.
FlowLab, our optional software for your PC, provides real-time curves and monitors flow, pressure, and volume parameters. It allows you to create automated test sequences, enhancing the efficiency of your devices and saving time during testing.
Additionally, you can generate customised test reports and record parameters for over 100 hours for detailed analysis and documentation.
The FlowAnalyser PRO test sets come with comprehensive accessories suitable for calibrating and verifying mechanical ventilators and anesthesia machines.
