The pH value is an essential scientific standard used to measure the acidity or alkalinity of aqueous solutions. Defined as the negative logarithm of the hydrogen ion activity in a solution, pH values typically range from 0 to 14. A solution with a pH of 7 is neutral, while a solution with a pH below […]

A pH meter is primarily used to precisely measure the acidity or alkalinity of a liquid medium. It is a widely used, easy-to-operate, and simple laboratory instrument. However, various problems often occur during its use, such as fluctuating readings, calibration issues, problems with buffer solutions, etc. What are the causes of these issues? What is

Calibrating a pH electrode is critical to ensure the accuracy and reliability of measurements taken by a pH meter. Below is a detailed guide to performing pH electrode calibration: I. Preparation Before Calibration 1. Inspect the Electrode Check carefully for any physical damage, such as cracks or air bubbles. Ensure the internal reference electrolyte solution

A device that converts physical measurement signals or ordinary electrical signals into standard electrical signals for output or can be output in the form of communication protocols. Generally divided into: temperature/humidity transmitters, pressure transmitters, differential pressure transmitters, liquid level transmitters, current transmitters, electrical quantity transmitters, flow transmitters, weight transmitters, etc. The hydraulic transmitter measures the

A pH meter, also known as an acidity meter, consists of two parts: an electrode and an electric meter. If the electrodes can be properly maintained, standard buffers can be prepared as required, and the electric meter can be operated correctly, the pH indication error can be greatly reduced, thereby improving the reliability of chemical
