WebpH Measurement Procedure using the Beckman 660 pH Meter. NOTE: When measuring the pH of potable water, purified water, Reverse Osmosis, or WFI, add 4M KCl to each sample (approximately 30 µL to 70 µL of 4M KCL per 100mL of water sample). 1 drop is ~ 10 µL. Addition of ions is necessary to obtain an accurate measurement of pH. WebExpect the following steps to occur during your procedure: 1. An esophageal motility test will first determine correct placement of the impedance pH probe. This involves inserting a very small catheter into the nostril and advancing it into the stomach. The catheter is withdrawn slowly as you take sips of water. sharpen clipper blades near me
