    PH Electrode Price List

    The electrode used in potentiometry is various pH electrodes, such as universal combination pH electrode, PTFE pH electrode, FGD pH electrode, pH glass electrode, high-temperature pH electrode, etc. ATO pH electrodes are accurate, high temperature resistant, acid and alkali resistant, and all at a reasonable price, below is the price list.

    How to Use & Maintain a PH Electrode?

    A pH electrode is a part of the pH meter contacting with a measured substance, it's usually used to measure the electrode potential. The service life of the pH electrode starts from the factory, regardless of whether it is used or not, the maximum service life is only 1 year, if the use and management methods are not in place, the service life will be shortened exponentially. This blog will tell you how to use, maintain, and storage pH electrodes.

    pH Meter Working Principle

    The pH meter is an important tool for measuring and reacting the pH of the solution, and the pH electrode can realize the function of detecting pH value and output signal by supporting the pH meter. There are various models and products of pH meters. The display mode is also divided into two options: pointer display and digital display. However, no matter how the type of pH meter changes, its working principle is the same. The main body of the pH meter is a precision potentiometer. A pH meter consists of a reference electrode, a glass electrode and itself.


    How to select a pH electrode?

    In industry, the pH meter is used more frequent as a pH measuring and analyzing instrument rather than the pH test paper and standard colour chart. The digital pH meter display screen can accurately show the pH value on real time, the error is greatly increased by one order of magnitude than that of pH test paper. Moreover, it can also realize the automatic control of pH value and pH value alarm. But due to the service life of pH electrodes, it is easy to break down, as a result, users have to pay much money in replace new pH electrodes. Next we will introduce the selection experience of pH electrode in several typical industries, so as to provide reference for users.

    What is a pH electrode?

    A pH electrode is a part of the pH meter contacting with measured substance. It's used to measure the electrode potential. Generally, there are two methods to measure the pH value of the aqueous solutions, namely Colorimetry (pH test paper and cuvette) and potentiometric method. The latter is the only way to realize continuous on-line measurement and process monitoring. Moreover, it can obtain accurate and repeatable pH value. The electrode used in the potentiometric method is called as primary battery, which is a system used to converse the chemical reaction energy into electrical energy, voltage of the primary battery is called for electrodynamic force (EMF).
