Each pack contains 20 individually sealed 20 mL foil pouches at a certified concentration of 12.88 mS\/cm (±10% at 25°C), 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.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eHighlights\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCertified 12.88 mS\/cm KCl Standard:\u003c\/strong\u003e Each pouch contains a 12.88 mS\/cm potassium chloride conductivity standard solution certified at ±10% at 25°C, 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.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSealed Single-Use Foil Pouches:\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eNo Preparation or Dilution Required:\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePortable, Spill-Resistant Field Format:\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eWide Conductivity Meter Compatibility:\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hach","offers":[{"title":"Default Title","offer_id":51675620081952,"sku":"2771520","price":6.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/3326\/9536\/files\/dpmAquaCheckSingletSingleUseConductivitySolution2771520.jpg?v=1779234174","url":"https:\/\/discountpoolmart.com\/products\/aquacheck-singlet-single-use-conductivity-solution-2771520","provider":"Discount Pool Mart","version":"1.0","type":"link"}
