5000 µS/cm (5.00 mS/cm) conductivity standard in single-use sachets — the high-range EC calibration point, and the EC value GroLine Quick Cal mode works with. Portioned fresh for every use.

Single-use sachets keep calibration solution factory-fresh — every calibration uses solution that has never been exposed to air or contamination. The light-blocking foil packaging protects against UV degradation, and each sachet is marked with its lot number and expiration date. Box of 25 sachets, 20 mL each.
