  PH Glass Electrode pH Glass Electrode: Principle, Structure, and Applications Introduction A pH glass electrode is a specialized electrochemical sensor used to measure the pH (acidity or alkalinity) of a solution. It is widely used in laboratories, industries, and environmental monitoring due to its accuracy, reliability, and rapid response. Principle of Operation The pH glass electrode works based on the potential difference that develops across a thin glass membrane when exposed to a solution. This potential difference is related to the hydrogen ion (H⁺) concentration of the solution, following the Nernst equation : E = E 0 + 2.303 R T F log ⁡ [ H + ] E = E_0 + \frac{2.303RT}{F} \log [H^+] where: E E is the measured potential, E 0 E_0 is the standard electrode potential, R R is the universal gas constant, T T is the temperature in Kelvin, F F is the Faraday constant, and [ H + ] [H^+] is the hydrogen ion concentration. The electrode potential is then c...

  PH Checker pH Checker: A Vital Tool for Measuring Acidity and Alkalinity A pH checker , also known as a pH meter or pH tester , is a device used to measure the acidity or alkalinity of a solution. It provides accurate pH readings, which are essential in various industries, including water treatment, agriculture, food production, medical applications, and laboratory research. How Does a pH Checker Work? A pH checker typically consists of a probe (electrode) and a digital display unit . The probe contains a special glass sensor that detects hydrogen ion activity in a solution. When immersed in a liquid, the probe generates an electrical voltage that corresponds to the solution's pH level, which is displayed on the screen. Types of pH Checkers Pen-type pH Testers – Small, portable, and ideal for quick field testing. Handheld Digital pH Meters – More accurate than pen testers, often used in laboratories and industrial applications. Benchtop pH Meters – Highly precise,...

  conductivity Sensor Conductivity Sensor: Principles, Types, and Applications A conductivity sensor is an instrument used to measure the electrical conductivity of a solution, indicating its ability to conduct electric current. It is widely used in water treatment, chemical processing, and industrial applications to assess water quality and the concentration of dissolved ions. Principle of Operation Conductivity sensors work based on Ohm’s Law , where conductivity ( σ \sigma ) is the inverse of resistivity ( ρ \rho ). The sensor measures how easily electric current passes through a liquid by applying a voltage and measuring the resulting current. Conductivity is expressed in Siemens per meter (S/m) or microsiemens per centimeter (µS/cm) for dilute solutions. Types of Conductivity Sensors Contacting (Electrode-Based) Conductivity Sensors Use two or four electrodes (typically made of platinum, graphite, or stainless steel). Apply an alternating current (AC) voltage and ...
