Conductivity Standards

Hach conductivity standards are offered in various packaging sizes, from 1 L bottles to disposable 20 mL Singlet packaging for on-site analysis. Singlet packaging ensures the product remains fresh and eliminates the possibility of contamination. All conductivity standards are traceable to NIST for optimal conductivity cell calibration. A special Certificate of Analysis is available for all Hach conductivity standards, which can be downloaded from www.hach.com: Support/Service, Certificate of Analysis menu using the product part number and lot number.

For critical applications and metrology needs, Hach offers Certified Standard Conductivity Solutions with a Conformity and Traceability Certificate provided by our Accredited Laboratory (www.hach.com/coa). The certificate shows the complete conductivity value along with the associated expanded uncertainty value (k=2). The solutions are formulated according to OIML and are traceable to basic electrical units through reference materials. Due to high-quality aluminum packaging, they have a very long shelf life.
