Oesophageal pH & Reflux Monitoring Devices

Oesophageal pH & Reflux Monitoring Devices

Understand and optimise reflux management with 24-hr pH and impedance monitoring.

Diagnosing patients with persistent reflux symptoms such as cough, heartburn, regurgitation and chest pain is often difficult using traditional pH monitoring.

The ZepHr® Total Reflux Monitoring System measures both pH and impedance giving reflux monitoring sensitivity approaching 90%1.  We call this unprecedented breakthrough ‘Total Reflux Monitoring’, because it delivers all the information you need for a precise, accurate assessment of acid and non-acid reflux as well as the correlation between reflux and symptoms.
