Description
The Hach Singlet 2771520 is a ready-to-use, single-use potassium chloride (KCl) conductivity standard solution designed for fast, accurate calibration of conductivity meters in pool, spa, aquatic facility, municipal water, and laboratory QA/QC applications. Each pack contains 20 individually sealed 20 mL foil pouches at a certified concentration of 12.88 mS/cm (10% at 25C), eliminating the preparation, storage, and contamination risks associated with bulk calibration solutions. The sealed foil packaging blocks air exposure and prevents solution degradation between uses, so every pouch delivers a fresh, reliable reference standard at the moment it is opened. Calibration is straightforward open a pouch, insert the electrode, calibrate the meter, and discard with no measuring, diluting, or cleanup required. The 2771520 is compatible with Hach conductivity meters and with most third-party conductivity and TDS meters.
Highlights
- Certified 12.88 mS/cm KCl Standard: Each pouch contains a 12.88 mS/cm potassium chloride conductivity standard solution certified at 10% at 25C, providing a reliable, traceable reference point for accurate conductivity meter calibration across pool, spa, municipal water, and laboratory environments where measurement accuracy directly affects water quality decisions.
- Sealed Single-Use Foil Pouches: Every 20 mL dose is sealed inside an individual foil pouch that blocks air exposure and prevents cross-contamination between calibrations, ensuring each procedure is performed with a fresh, uncompromised standard rather than a slowly degrading bulk reagent left open between uses.
- No Preparation or Dilution Required: Pre-mixed and pre-measured at the correct certified concentration, each pouch needs no dilution, mixing, or weighing on site open the pouch, insert the electrode, and calibrate dramatically reducing preparation time and the user-error risk associated with preparing calibration solutions in the field or lab.
- Portable, Spill-Resistant Field Format: The compact, sealed pouch format is easy to transport to pool facilities, waterparks, and remote field sites without the spillage and breakage risk of glass bottles, making the 2771520 a practical option for pool service professionals and water quality technicians performing routine on-site conductivity checks.
- Wide Conductivity Meter Compatibility: Designed for use across Hach’s full conductivity meter portfolio and compatible with most other conductivity and TDS meters on the market, making it a flexible calibration solution for both dedicated Hach users and operations that maintain a mix of instrument brands in their inventory.
