Buffers and standard solutions

pH Buffers and Conductivity Standard Solutions for laboratory and the field analysis

Whether in the laboratory or in the field, correct measurement results are essential. The basis for accurate measurements is good care and calibration of the electrodes. As well as proper handling, the standard solutions that are used are key.

HACH LANGE offers a large number of high quality buffer and standard solutions for pH and conductivity. The laboratory in Berlin where these solutions are prepared is DKD accredited, giving them the seal of approval.
