Meinsberg Electrodes for Laboratory and Process

Product catalog summary
Introduction
Meinsberg has a long history of over 65 years in developing electrochemical sensors in Saxony, Germany. This document outlines the instructions and specifications for various laboratory and process electrodes, including pH, redox, conductivity, oxygen, and chlorine sensors.
Storage
pH and redox combination electrodes should be stored in a 3 mol/l or saturated KCl solution and must not be stored in deionised water.
Calibration
The calibration process involves rinsing the sensor with deionised water, immersing it in a buffer solution, ensuring temperature consistency, and rinsing before switching buffers. Used buffer solutions should be disposed of properly.
Cleaning
Sensors should be cleaned with water and dried with a paper towel. For oily or organic contamination, ethanol is recommended, while protein contamination requires a pepsin cleaning solution. Rinse with deionised water and store in the storage solution. Calibration is necessary before the next measurement.
Reconditioning
Electrodes with decreased slope or slow response should be immersed in a reconditioning solution for up to 2 minutes, avoiding diaphragm wetting. Rinse with deionised water and store in the storage solution for 1 hour. Calibration is required before the next measurement.
Order Codes
Electrodes come with various plug and cable options, with standard cable lengths ranging from 1 m to 15 m. Special lengths can be specified, and detailed order codes are provided for different configurations.
Electrode Types and Applications
A selection table is included for laboratory and process applications, detailing suitable electrodes for environments such as aquariums, biotechnology, and cosmetics.
Technical Data
Technical specifications for pH and redox combination electrodes include details on shaft material, length, diameter, temperature sensor presence, membrane shape, and reference electrolyte concentration.
Conclusion
This document serves as a comprehensive guide for selecting, storing, calibrating, and maintaining Meinsberg electrodes for laboratory and process applications.
Measuring Principle and Specifications
2-Electrode Technology: Used for measuring conductivity with cell constants of 0.1 cm-1 and 1 cm-1, suitable for low ionic mediums and broader applications, respectively. The measuring range varies, and both types operate within a temperature range of -5 to 100°C.
Oxygen Sensors: The MF 41-N model is designed for aqueous solutions, featuring corrosion resistance, an integrated temperature sensor, and a robust plastic shaft, operating on the amperometric principle.
Applications
Suitable for low ionic mediums like distillation plants and ion exchangers, and general water applications including drinking water, surface water, waste water, sea water, swimming pools, and beverages.
Electrical Connections
Electrodes can be configured with various plug connectors, cable lengths, and threads, with standard configurations including the SMEK lab plug head and fixed cable.
Technical Data for Electrodes
Various models are available for different applications, featuring gel electrolytes, ceramic diaphragms, and compatibility with S7 coaxial plug heads.
Connection Cables
Standard cable lengths range from 1 m to 15 m, with special lengths available. Various cable types are specified for different sensor connections.
Temperature Sensors
Platinum temperature sensors (Pt 100 and Pt 1000) are available, compliant with DIN EN 60751, class A, suitable for fluids with a temperature range of -10 to 100°C and pressure below 6 bar.
Order Information
Order keys and configurations are detailed, with specific illustrations provided.
Data Summary
The document contains numerical data points representing measurements or specifications across different conditions or time intervals.
Special Design Sensors
Meinsberg offers the capability to manufacture sensors in special designs based on customer requests, including oxygen/temperature sensors for composting plants and conductivity cells for special applications.
Other Product Lines
Meinsberg offers various other product lines, including laboratory multi-parameter systems, potentiostat/galvanostat, corrosion measuring cells, controllers, and more.
Contact Information
Sensortechnik Meinsberg GmbH is located in Germany, with contact details provided for telephone, fax, and email.
