The new electrode series ProcessLine 9xx with PTFE junction as available as both an analog and Memosens® model is the universal solution for pH measurement in process and environmental applications. The electrodes of this series work reliably and accurately, even in the most demanding media and hazardous environments. They are ideal for use in chemical industrial settings, breweries, the food industry, waste incinerators, the paper industry, power plants or plastic chemistry. 1 Screw plug head with Memosens® connection (Alternatively analog electrodes with VP or coax plug head (for...

New: Single-rod measuring cell with Liquid potassium chloride delivery In demanding media with a very low conductivity in the low μS/cm range or with suspended solids up to extreme pH values, we recommend the use of pH electrodes with a liquid KCl reference electrolyte. This electrolyte is emitted to the measuring medium via the junction. This reduces junction potential leading to a more accurate measurement. The electrodes of this series work reliably and accurately, even in complex applications. Whether it be in the chemical industry, the food industry, biotechnology, waste incinerators,...

New: MEMOSENS® Sensors Our Memosens® program contains pH and ORP electrodes. These sensors are compatible with all Memosens® transmitters and meters available on the market. Our Memosens® sensor portfolio includes our already established ProcessLine, SteamLine, and annular-gap electrodes as well as our new FlowLine series. FlowLine is a new line of liquid-electrolyte sensors with integrated pressure adapter for hose connection fo an electrolyte reservoir. All low-maintenance Memosens® electrodes conform to ATEX standards 94/9/EG. Inspection at the EXAM in Bochum/Germany was documented with...

New: CHEMtrac 840M Ball valve armatures The CHEMtrac 840M is a manually driven retractable holder made from stainless steel to install Pg 13.5 Ø12 mm sensors in tanks or pipelines. The advantages: • ew manual replacement fitting series with a N mechanical linear drive for the safe retraction and extension of the sensor without interrupting the process • ustomizable to application conditions C with multiple process connection, cleaning connection, and seal material options • o special sensors necessary. Designed N for low maintenance electrodes with an installation length of 120 mm, a...

1.2 Tips and hints for successful measurement with pH and ORP electrodes Structure of pH single-rod measuring cells Problem solution. However, the measurement signal can only be measured against a reference electrode. The reference electrode ideally has a stable, con- Users can select from a variety of different electrodes for pH measurement. The selection often becomes the problem. It is therefore important to understand the components of the pH electrodes including their features, so that the best electrode can be found for the application. Conduction electrode Inner buffer with KCI...

Conclusion Only an electrode matching the application achieves the best measurement reliability and maximum service life. It is especially important to pay attention to the type of junction in the selection of the electrode. The junction establishes the connection between the electrode and the measuring medium. For example, the platinum junction used in sensors with liquid electrolyte, provides a fast and stable measurement with it's defined electrolyte flow and resistance to penetration of the measurement medium, is for general use. Reference systems of pH electrodes Problem Besides glass...

pH glass types Problem There are many different pH membrane glass types available. Each pH glass has specific qualities so it should be chosen carefully to suit the measurement application. Question What different kinds of pH glass are available? What are the main characteristics of these membrane glasses and which is recommended for a particular measurement application? Answer Over time the glass membrane of a pH glass electrode changes. Because of exposure to water, alkali ions dissolve from the glass surface and oxide groups of the silicate become OH groups which causes a gel layer. This...
