Frequently Asked Questions

What conductivity value does this solution reference?

This solution is calibrated to 1413 µS/cm (microsiemens per centimeter), a widely used single-point conductivity calibration standard.

Is this solution NIST traceable?

Yes - Hanna uses NIST-traceable potassium chloride and certified manufacturing equipment to ensure traceability of every batch.

What is the shelf life?

Unopened bottles carry a five-year shelf life. Each bottle is labeled with a lot number and expiration date for traceability.

Why does the label include a temperature chart?

Conductivity values shift with temperature. The temperature chart shows actual conductivity at various temperatures so you can calibrate accurately under your specific conditions.
