- Overview

High-quality, easy-to-use pH and Impedance-pH catheters for esophageal and gastrointestinal reflux measurement.


ISFET Impedance-pH catheters

We offer a full range of ISFET-based disposable Impedance-pH catheters to measure acidic, weakly acidic and non-acidic gastro-intestinal reflux causing GERD.

ISFET stands for ION-Sensitive Field-Effect Transistor technology. ISFET is a proven technique and provides very accurate calibration and pH measurement.

The ISFET Impedance-pH catheter line contains catheters with 6 Impedance channels and 1 or 2 pH sensors. This enables reliable recording of intra-esophageal and gastric pH. ISFET catheters have an internal reference which provides greater ease of use.
