Frequently Asked Questions

What conductivity value does this solution reference?

This solution is calibrated to 1413 uS/cm (microsiemens per centimeter), a widely used single-point conductivity calibration standard. It suits most hydroponic and general-purpose EC meters.

Is this solution NIST traceable?

Yes -- Hanna uses NIST-traceable potassium chloride and certified manufacturing equipment to support traceability for every batch. Each bottle carries a lot number so a specific batch can be traced if needed.

How long is the shelf life?

Unopened bottles carry a five-year shelf life, and each bottle is labeled with a lot number and expiration date for traceability. Once opened, use the solution within the timeframe printed on the label.

Why does the label include a temperature chart?

Conductivity values shift with temperature, so the chart shows actual conductivity at various temperatures. This lets you calibrate accurately under your specific room or reservoir conditions.
