How to choose pH electrode for 11375-G1A2A2 4-250MM
PH electrodes and transmitters are widely used in many industries, such as chemical, water and wastewater, food and beverage, pharmaceutical, power, metallurgy, and oil and gas industries. Select electrodes based on the application. Select the diaphragm and reference system for the glass electrode as needed. Use ISFET electrodes in media with unavoidable glass breakage or high organic solvent content. Enamel electrodes are suitable for applications with low long-term stability and minimum maintenance requirements.
Based on the principle of potential measurement, the pH value of a liquid can be calculated. The video introduces the principle of measurement.

MakePH electrode/E+H water analysis electrodePH measurement using glass electrode and enamel electrode
PH value is the unit of measurement for the acidity or alkalinity of a liquid medium. The pH sensitive component in glass electrodes is the glass bubble, which can generate an electrochemical potential corresponding to the pH value of the medium. A small amount of H+ions penetrate through the outer layer of the membrane, while negative ions remain in the solution, thereby generating a potential.

The glass pH electrode integrates an Ag/AgCl reference system as a reference electrode required for pH measurement. Calculate the pH value using the Nernst equation based on the potential difference between the reference system and the measurement system. Our pH electrodes and transmitters have excellent linear measurement performance over a wide pH range!

The measurement principles of enamel pH electrodes and glass pH electrodes are similar, except that enamel pH sensitive components are used.

Using ISFET electrodes for pH measurement
Measure pH value using ion selective field-effect transistor (ISFET). It is a transistor with a source and drain, separated from the substrate by a semiconductor. Hydrogen ions in the medium will accumulate on the substrate. The positive charges generated on the outside of the substrate form a 'mirror image' with the negative charges on the inside of the substrate. Thereby making the semiconductor channel conductive. The more H+ions accumulate on the substrate, the greater the current flowing between the source and drain electrodes.

advantage
Our pH electrodes and transmitters meet all requirements from basic functionality to multi-channel, multi parameter measurement.

The pH buffer solution, pH solution, and pH standard solution we provide all have very high accuracy. They were prepared in our own long-term calibration laboratory, which was successfully certified by DAkkS (a German certification body). Different types of electrodes use different membranes and reference systems, ranging from anti fouling PTFE membranes to high-sensitivity ceramic membranes to anti clogging perforated membranes. We provide pH mounting brackets that meet various application requirements: fixed mounting brackets, immersion mounting brackets, flow-through mounting brackets, and extendable mounting brackets.

The fully automatic calibration, adjustment, and cleaning system ensures optimal performance of pH electrodes and transmitters in chemical processes, pharmaceutical production, or sanitary applications.

Trustworthy and reliable measurement results

Endress+Hauser has successfully passed the certification process of the German Accreditation Service (DAkkS) and meets the requirements of DIN EN ISO/IEC 17025:2005 standard. The pH calibration solution produced by our certified calibration laboratory can meet demanding customer requirements and ensure the reliability of your pH measurement.

PH calibration solution meets the requirements of more demanding working conditions

The measurement accuracy of pH measurement points mainly depends on the correct use of pH calibration solution for calibration. Endress+Hauser produces pH calibration solutions that meet the strictest requirements, with a deviation of ± 0.02 pH between the actual value and the specified accuracy. The calibration solutions are traceable, comply with NIST (USA) and PTB (Germany) standards, and use FDA listed preservatives. Endress+Hauser regularly participates in international circulation testing to ensure the quality of calibration solutions.

Production of certified pH calibration solutionPH electrode/E+H water analysis electrode

DAkkS has fully certified the production of our calibration solution and granted us a pH calibration laboratory calibration license (DAkkS certificate number: D-K-15 193) located in Waldheim, Germany. The certification ensures precise deviation between actual values and calibration solution. In addition, we provide certificates for the pH calibration solution we produce, aiming to simplify the audit process and improve the reliability of standard operating procedures.PH electrode/E+H water analysis electrode
