Ph with impedance
WebMar 1, 2024 · Patients with chronic heartburn or other suspicions for gastroesophageal reflux disease (GERD) may be asked to undergo a 24-hour pH/Impedance test. This exam quantitatively measures the amount and chemical nature of reflux episodes during a twenty-four hour period. WebAmplifier U1 off sets the pH electrode by 512 mV. This is achieved by using TI's LM4140A-1.0precision micro-powerlow-dropoutvoltage reference that divider. The output of amplifier U1, that is set up in a unity-gainconfiguration, biases the reference electrode of the pH electrode with the same voltage, 512 mV, at low impedance. The pH-measuring
