Hach conductivity standards are available in a variety of packaging sizes from 1 L bottle down to single-use 20 mL Singlets for on-site analysis. Singlets assure freshness and eliminate the possibility of contamination. All conductivity standards are NIST traceable for optimum conductivity cell calibration. For all Hach conductivity standard, a specific Certificate of Analysis is available for download from Support/Service, Certificate of Analysis menu using product part number and lot number.

For critical applications and metrology needs, Hach offers Certified Conductivity Standard Solutions with Certificate of Conformity and Traceability from our Accredited Laboratory ( The certificate is reporting the exact conductivity value with related expanded uncertainty (k=2). Solutions formulated according to OIML and traceable through the reference material back to the fundamental electric units. They are offering a unique extended shelf-life period thanks to a premium aluminium packaging.
