The Digitrapper  pH-Z recorder with combined  pH-impedance provides total reflux monitoring, allowing you to differentiate acid and non-acid reflux in patients with an array od symptoms.

Ambulatory reflux monitor ng is the only test that allows for determining the presence of abnormal esophageal acid exposure, reflux frequency and symptom association with
reflux episodes

Combining impedance and pH monitoring improves the detection and characterization of GERD. The frequency, duration, clearance and extent of reflux can be evaluated

The advantages of 24-hour pH-impedance include the ability to simultaneously assess the adequacy of acid suppression, analyze persistent symptom association with acid or non-acid reflux episode frequency
