The NIST/DIN pH buffers are specified to three decimal places, for example 9.180, offering the highest possible pH precision.

• Used for calibration/verification purposes
• Uncertainty: ±0.015 pH

A detailed test certificate is available for every bottle and guarantees the tested values and traceability.

Single-use sachets, filled under controlled conditions, guarantee a fresh and uncontaminated solution for every calibration. The round and large opening of the sachets allows for easy sensor insertion and makes calibration a quick and simple task.
