This is an Analog pH Meter Kit with industrial real-time online electrode, specially designed for Arduino and other Microcontrollers. It uses an industry electrode and has built-in simple, convenient, practical connection and long life (up to 1 year), which makes it very suitable for long term online monitoring. It has an LED which works as the Power Indicator, a BNC connector and PH sensor interface. To use it, just connect the pH sensor with BNC connector, and then plug the PH interface into the analog input port of any microcontroller or Arduino controller. If programmed, you will get the pH value easily. Or can measure the voltage on the multi-meter.
PH indicates the sample's acidity but is actually a measurement of the potential activity of hydrogen ions (H+) in the sample. PH measurements run on a scale from 0 to 14, with 7.0 considered neutral. Solutions with a pH below 7.0 are considered acids. Solutions with a pH above 7.0, up to 14.0 are considered bases. All organisms are subject to the amount of acidity of stream water and function best within a given range.
This industrial pH electrode is made of sensitive glass membrane with low impedance. It can be used in a variety of PH measurements with fast response and excellent thermal stability. It has good reproducibility, is difficult to hydrolysis, and can eliminate basic alkali error. In 0pH to 14pH range, the output voltage is linear. The reference system which consists of the Ag/AgCl gel electrolyte salt bridge has a stable half-cell potential and excellent anti-pollution performance. The ring PTFE membrane is not easy to be clogged, so the electrode is suitable for long-term online detection.
