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.
