Conductivity Standards


AccuSPEC Conductivity Standards respond to the need for the accurate measurement of conductivity in laboratory, process, & environmental water samples. All standards are certified at 25 °C.

• Numerous concentrations available

• Direct Traceability to NIST

• Certificate of Analysis with actual conductivity, lot number,
  expiry date and traceability to NIST, where applicable

• Reduce errors by selecting closest concentration

• Product confidence

• Complete documentation for audit purposes
