HI50036P GroLine Quick Calibration Solution (25 × 20 mL Sachets)
This convenient calibration kit provides 25 single-use, individually packaged sachets for GroLine pH and/or EC/TDS meters. Each sachet is foil-sealed with light-block protection and prints the lot number and expiration date for guaranteed freshness and reliability. It features a dual-purpose solution: pH 6.86 buffer and EC standard at 5,000 µS/cm, enabling one-step single-point calibration for both pH and conductivity sensors using the Quick Cal function of compatible meters.
Packaged for portability, this kit is ideal for fieldwork or infrequent calibration use. Unopened sachets remain stable for up to five years from manufacture, ensuring long-term accuracy and readiness when needed.
