Discover the differences between NIOX® and other devices
Fully conforms to the ATS & ERS Standards1
With no unexpected servicing, reconditioning, and direct NO measurement, NIOX® is designed with healthcare professionals in mind, whether that is primary care or secondary care.
Fully conforming the ATS & ERS standards, the integrated NIOX NeutroNO™ scrubber truly removes ambient nitric oxide on inhalation, alongside only taking in the last few seconds of the exhalation flow to analyse the lower airways.1-4
NIOX®’s pre-calibrated sensors eliminate downtime, have no servicing, recalibration or waiting, and are always ready.
As a standalone desktop device, NIOX® can be used plugged in or on its all-day battery life, making it ready for testing on the go.
Only compared with FeNO devices that are both FDA / CE approved.

NIOX® is the only portable device to fully conform to the ATS & ERS standards for FeNO testing.1 Which is one of the reasons, it is the technology of choice!1
NIOX PRO® is designed by NIOX® but inspired by you. This is the best FeNO testing experience that NIOX® has ever engineered, and you can only get that with NIOX®.
Featuring in the most clinical studies, and used by thousands of healthcare professionals around the world: NIOX® technology is considered the gold standard.1,14,15
Some FeNO devices estimate FeNO using gas conversions and complicated algorithms. With NIOX®, we simply measure NO directly.
NIOX® devices are pre-calibrated, so no waiting between tests, and no servicing or maintenance is required. Never worry about downtime with NIOX®.
Our commercial model is transparent, meaning that there are never any hidden costs. Our quotes are accurate, like our devices.11
The new larger screen and refinements based on feedback on NIOX VERO® lead to an improved user experience.
Designed to feel familiar, yet entirely new, NIOX PRO® introduces a reimagined software experience to improve useability.
NIOX PRO® introduces Bluetooth® version 5.0, and USB type C, which allows for connectivity with Windows, iOS, iPadOS, Android, MacOS and Linux.
NIOX PRO® has an additional 20% longer life when compared to NIOX VERO®, meaning that you can keep testing FeNO for even longer!
NIOX® is designed to support efficient clinical workflows, delivering accurate and reliable FeNO measurement in just one test.11,13,16 Make the switch to NIOX® today.
