WebbHamilton laboratory pH sensors and electrodes are precision instruments known for high quality, long lifetime, and remarkable performance in a wide range of applications. … WebbFor the 24-hour probe study, your healthcare provider will insert a thin tube into your nose. The tube goes down into your esophagus. The tube will have multiple sensors on it. The sensors read your pH levels and the location of both air and liquid in your esophagus as it flows up from your stomach. Once the tube is in place, you can go home.

WebbAccurate measurement of pH in small samples relies on careful sensor selection and choice of measurement techniques. These guidelines can help you to successfully overcome the challenges of small volume measurements and achieve accurate, repeatable results. Download an Application Note to learn about pH measurement in small samples: WebbIdeally the pH sensor should be clean at all times in order to guarantee an ideal pH measurement. Periodic cleaning of the pH probe should be part of any regular plant maintenance schedule. Since the cleaning frequency depends solely on the goals of the application, a cleaning cycle time has to be established individually for each pH …

WebbThe first thing you should do is test your probe with a small amount of buffer solution solution of known pH and if it reads the buffer pH accurately, you are good to go, and if not, you need to calibrate the pH meter before proceeding.
