Hanna Quick Calibration Solution Sachets — 25 × 20 mL

Quick Cal is Hanna's one-solution calibration for GroLine testers: a single standard with a pH value of 6.86 that also calibrates conductivity to 5,000 µS/cm, so a pH/EC meter calibrates both parameters in one dip — in single-use sachets (HI50036P) that are fresh every time.

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.

Please note: Hanna Instruments items may add 1-2 extra business days of processing time before shipping.
