A pH buffer is a reference solution of known pH value that is used for sensor calibration. pH buffers are key to ensuring accurate pH readings. Select from our comprehensive range of accurate pH calibration solutions, from technical buffers, buffers certified by an accredited body (DAkkS), to NIST/DIN buffers for high precision. To minimize contamination risk, choose small bottles or single-use sachets.
We support and service your measurement equipment through its entire life-cycle, from installation to preventive maintenance and calibration to equipment repair.
*The tolerances are only for the buffer and not for the entire pH measurement of a sample.
We offer buffer sachets (small volume packaging of 20mL) that are easy to use and guarantee fresh solutions for every calibration. Each sachet box comes with a printed certificate.
When measuring the pH value of a sample, gently stir the sample to ensure that it is homogeneous. It is important that calibration and measurement are done under the same conditions.
