Accredited pH laboratory

Correct results you can rely on Our permanent calibration laboratory for pH quality buffers meets most stringent customer requirements. Endress+Hauser has passed the exacting accreditation process run by the German Calibration Service (DKD) in accordance with the specifications of DIN EN ISO/ IEC 17025:2005. This accreditation guarantees our customers even greater reliability in pH measurement. The accuracy of a pH measuring point depends on correct calibration with pH buffer solutions. Endress+Hauser produces pH buffer solutions for the most stringent requirements, which are specified with the actual value and an accuracy rating of ±0.02 pH.

On August 31, 2020, the accreditation body renewed the calibration license with DAR registration number D-K-15193-01 for the permanent laboratory in Waldheim. This accreditation is regularly repeated and confirms that the actual values and deviations of the buffer solutions produced are correctly determined. In addition, the quality buffers meet the strict requirements of the pharmaceutical industry and contain only FDA-listed preservative agents. Users in the chemical, food and water/wastewater industries also benefit from the reliability of the calibration solutions.
