Uptime of Your pH Measurement System –
Regularly Calibrate and Maintain Your Sensors
Sensor calibration is crucial and we recommend determining the status of your calibration slope and offset on a daily basis. Always use fresh calibration solutions to minimize measurement uncertainty and to optimize the reproducibility of your results. Get useful tips on sensor selection, calibration, and maintenance in our Good Electrochemistry Practice™ (GEP) program.
Intelligent Sensor Management –
Easy Handling, Data Security, and Lifetime Monitoring
Intelligent Sensor Management (ISM®) is a sophisticated safety concept that leaves nothing to chance. With this technology, the instrument will automatically detect a connected sensor and will use the most up-to-date calibration data stored on it. Further information concerning lifetime is monitored. However, the clearest indication that the sensor has reached its end of life is a reduced calibration slope.
Sensors
Sensors for pH, conductivity, ion concentration, dissolved oxygen, and redox potential.
 |  |  |
Laboratory pH Sensor | Laboratory Conductivity Sensor | Ion-Selective Electrode |
Routine to highly-specialized pH sensors provide accurate readings for a wide range of laboratory and field applications. | Robust conductivity sensors for precise determination across the entire conductivity range. | Quick and easy determination of the concentration of a variety of dissolved ions and gases. |
 |  | |
Dissolved Oxygen Electrode | Laboratory ORP Sensor | |
Optical and polarographic electrodes for reliable determination of dissolved oxygen concentration. | Accurate and reliable sensors that measure the Oxidation Reduction Potential (ORP). | |
pH Measurement Accuracy –
Highly Dependent on Your Calibration Habits
pH measurements are only as accurate as the buffer solutions used for calibration purposes. in addition, the quality of a solution is only guaranteed for unopened bottles that have not yet expired. No matter if you are looking for traceable technical buffers, or buffers that are certified by an accredited body, you will find the right solution. Maximum accuracy is guaranteed with our NIST/DIN buffers. GEP offers useful tips on how to optimize the use of calibration solutions.
