Oakton Traceable® Conductivity and TDS Standard

These standard solutions let you calibrate conductivity instruments to ensure accuracy. Use when readings are expected to be around 5 µS/cm. Average accuracy at 25° C is ±0.25 microsiemens for 1, 5, 10 microsiemen (µS) solutions, or ±0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater. NIST-traceable reference materials.
