• NIST standardized and cross checked 3 ways for certifiable accuracy and reliability
• Include 3 equivalent TDS calibration values
• Economical bottle: each contain a full pint of high quality, premixed calibration standard
• Single-use pouches: TDS "Single" is filled with 20 mL of calibration standard that stays fresh and free from contamination

Oakton conductivity / TDS calibration solution come premixed and ready to use. The solutions are standardized against NIST certified references to ensure your confidence. They include ppm values and conductivity-to-TDS conversion factors of KCl, NaCl and 442 (simulates natural freshwater). They are also labeled with the name and CAS number for all ingredients to conform to "Right-to-Know" requirements.

Choose from economical solutions bottles, or convenient Conductivity "Singles" solutions in pouches. Each on-pint polyethylene (recyclable) bottle is labeled with a Conductivity vs. Temperature reference table for easy temperature coefficient determination, and includes an MSDS (Material Safety Data Sheet). Each pouch contains 20 mL of ready-to-go conductivity calibration solution or deionized rinse water. Since pouches are opened individually, these solutions are guaranteed to be contamination free, every time!

Conductivity/TDS solution bottles, 1 pint of premixed calibration solution in recyclable PE bottle. ±1% accuracy at 25ºC. Shipping weight 1.1lbs/510g each
