Extremely robust and accurate flow results are delivered without calibration thanks to our TrueFlow™ technology integrated into the EasyOne Pro® LAB.
- Self-Quality Control through TrueCheck™ Technology
With EasyOne Pro® LAB you can fully focus on the patient. TrueCheck™ ensures that each gas measurement is accurate without calibration and warm-up time.
- Compact & Lightweight Design
Weighing only 18 lbs. (9kg), the EasyOne Pro® LAB is compact & durable – without compromising quality. It easily fits in any office setting.

"We are over-the-top satisfied with ndd's EasyOne Pro.
The EasyOne Pro is easy to use, easy to assemble, and is great for large and claustrophobic patients. The EasyOne Pro saves a huge amount of floor space, and it's portable.
We've had many patients say they will never go back to the surrounding hospitals because of the convenience of testing with ndd's EasyOne Pro (and the fact that they don't have to enter that uncomfortable PFT body box)."Sarah RaileRRT/Wray Hospital and Clinic - Banner Health
"The pulmonologist that tests at our facility is impressed with the EasyOne Pro, as the testing results are spot-on with a similar PFT test done in a traditional body box. We would go with the Pro over a traditional body box any day."Sarah RaileRRT/Wray Hospital and Clinic - Banner Health
"We recently acquired several EasyOne Pros for three hospitals in Madrid. Given the current situation [COVID-19], this equipment guarantees proper cleaning & disinfection between patients. In addition, it's very easy to use, something the Team very much appreciates - it's portable, and it brings the highest accuracy. An excellent medical device."Dr. Rodríguez-MoroPrincipe de Asturias University Hospital
“Being on a truck we really like equipment that can be mobilized. It has to be small, it has to be able to be moved around without breaking, it has to be reliable. When I did the research, the EasyOne Pro was being used in that capacity for other outreach clinics and I thought we should invest in that for our trucks. It has been a great decision actually. It’s very easy to use, reliable and accurate.”Dr Rolf GomesFounder of Heart of Australia & Cardiologist
"We see that ndd technology is always accurate when comparing it to simulator data or biological control values. In addition to the outstanding accuracy the ndd software is very user-friendly, which makes ndd devices easy to use.”Alejandro Casas MD, Ph.DGeneral Director, Colombian Pulmonological Foundation/Former President, ALAT (Latin American Thoracic Association)
"My clinical research on asthma and COPD happens at the point of care in some of the most remote, resource limited places in the world. Because of this, I need highly portable, very durable diagnostic devices reporting consistent and accurate results even under the toughest conditions. I use ndd’s devices because I know no matter the condition, the device will report accurate results."William Checkley, MDAssociate professor at John Hopkins Bloomberg School of Public Health
"Our academic activities related to trainings and continuous learning for the specialists that take care of the respiratory health in our region, are supported by new technologies. Our experience with ndd devices has been very positive because they adapt to our necessities, they are always updated regarding new standardization and technological advances."Gustavo GiraldoPublic Relations and Marketing Manager/Asociación Latinoamericana de Tórax (ALAT)
"The EasyOne Pro’s portability and ability to accurately perform mobile PFTs in under 30 minutes make it the perfect device for this type of clinic. It allows us to use the patients’ time more efficiently, better understand their illness, and improve assessment of their condition. It’s easy to operate and allows us to provide prompt and accurate assessment of patients’ lung function.”Anoop Nambiar, MDMedical Director of the San Antonio Pulmonary Fibrosis Support Group and Director of the University of Texas Health Science Center at San Antonio Center for Interstitial Lung Disease.

FAQs EasyOne Pro® LAB
The EasyOne Pro LAB is exactly the same as the EasyOne Pro, except that it has the capability to perform the multi-breath washout (MBW) test. This test requires additional sensors and the use of 100% Oxygen.
To add a filter (2) to the EasyOne Pro, insert the (1) Spirette FA Pro/LAB into the EasyOne Pro handle. Then attach the filter to the Spirette FA Pro/LAB, as shown in the diagram below. If you have questions about how to connect or use ndd filters, please contact ndd customer support in North America at [email protected] and internationally at [email protected].

You can find the product specification on the respective product pages. The specification contains a list of all supported normal values.

All EasyOne products are designed to require no calibration and minimal maintenance. The device is designed to remain in calibration throughout its lifetime. No calibration procedures are required prior to testing. Our TrueFlow ultrasonic technology assures accurate volume and flow measurements every time. And our unique automated TrueCheck process assures that all gas measurements are accurate for each test. You may choose to use the optional 3-liter calibration syringe to verify volume and flow accuracy, as recommended by ATS/ERS.
Yes. ndd’s products are all completely HL7 compatible enabling connectivity to virtually all EMRs. We would be happy to work with you to configure an interface for your particular EMR system. We are also constantly working to expand our library of dedicated integrations. For more information on connectivity with your particular EMR contact our Technical Support team.
A PFT session including spirometry and DLCO generally takes less than 20 minutes.
The EasyOne Pro/LAB is compatible with virtually all PC-style USB printers, without the need for external driver installation. The printer can be connected directly to a USB port on the rear of the device. We can sell you a printer with the device, or you can supply your own.
You can also connect the device to your network where it will automatically find any connected, compatible printers avoiding the need for a dedicated printer for your PFTs.
Spirette: Each test performed requires the use of a spirette. This is a single-patient-use mouthpiece which ensures that no contamination can reach the internal flow path of the device. This means that no cleaning is required between patients, and no calibration, ever. Simply toss the spirette after each test session.
Barriette: For a DLCO test, in addition to the spirette, you will need to use a barriette. This protects the valve and hose system from contamination, eliminating the need for cleaning between patients.
FRC barriette: This is similar to the DLCO barriette, but used only when performing a multi-breath washout test.
Gasses: The DLCO test requires a standard medical grade DLCO gas mixture consisting of 0.3% Carbon Monoxide, 10% Helium, 21% Oxygen, remainder Nitrogen. The multi-breath washout test requires 100% Oxygen. These gasses are readily available from your local medical gas supplier in various tank sizes. We will assist you in selecting the appropriate tank regulators required for connection to the device.
The device itself is self-contained and measures only 270 x 335 x 270 mm (10.6 x 13.2 x 10.6 inches) (h x w x d). No additional PC, monitor, keyboard or control unit is required. This allows it to easily fit on a counter. You will also need to allow for storage of the gas tank(s) which come in a variety of sizes, and can usually fit comfortably in a corner, or under the counter.
The EasyOne Pro/LAB is designed to require minimal maintenance. The annual replacement of four external components is ALL that is required to keep the system running smoothly. These components are available as a convenient kit. Installation is done in minutes and requires no special tools.
Data can safely be exported by using the “Export Data” feature or “Backup” feature within the Storage tab in the configuration.
