We recommend using pH buffers only once. If you want to use the same buffers for more analyzers, then you must avoid contamination of the buffers by the sensors. The sensor must be cleaned and washed carefully before inserted into the buffer. A sensor is often cleaned with acid or with detergent to remove the fouling or the scaling. After this chemical cleaning it must be washed with demineralized water. This must be done three times with fresh water before it can be considered clean. The sensor must also be rinsed with demineralized water between the two buffer solutions. Then you can calibrate up to 10 sensors with one set of buffers as long as it is in a short time.
