LIQUID PH TESTING SENSOR MODULE PH0-14

This is an Arduino Liquid pH Value Detection Sensor. The pH stands for hydrogen power, and it is used to determine the concentration of hydrogen ions in the body. This is used in the testing of water quality and aquaculture. The pH scale goes from 1 to 14, with 7 being considered neutral. Acidic solutions have a pH less than 7, whereas basic or alkaline solutions have a pH more than 7.

A single cylinder makes up this tester with a PH electrode. It may be connected directly to the input terminal of a pH metre, controller, or any other pH device with a BNC input terminal. The pH electrode probe in the device provides precise and dependable readings that are virtually immediate. The potential activity of hydrogen ions (H+) in the sample is used to determine the acidity of the sample. pH is measured on a scale ranging from 0 to 14, with 7.0 being considered neutral. Acidic solutions have a pH of less than 7.0. Solutions having a pH of greater than 7.0 but less than 14.0 are classified as bases.

This industrial pH electrode is made up of a sensitive glass membrane with low impedance. It offers fast response and excellent thermal stability making it suitable for various pH measurements. It features good reproducibility, is difficult to hydrolysis, thus eliminating basic alkali error. The output voltage is also linear within the range of 0 pH to 14.  The electrolyte present in the reference system consists of the Ag/AgCl gel electrolyte salt bridge. Moreover, It has a stable half-cell potential and excellent anti-pollution performance.
