Conductivity Standards

Conductivity Standard

For measurements in the low conductivity range stable and reliable calibration standards have been completely lacking up to now. Since a conductivity standard is not a buffer solution, the lower the value of the conductivity standard, the greater the effect of entry of CO2 or contamination. Hamilton is the first manufacturer to offer patented conductivity standards of 1.3 and 5 µS/cm with a certified accuracy of  ±1% and a lifetime of 1 and 3 years, respectively. The procedure for determining conductivity was developed in collaboration with DFM. Many metrological institutes choose Hamilton standards because of their unprecedented stability and independent verification by PTB. During an interlaboratory test among prestigious European metrological institutes Hamilton standard were used as measurement solutions.

Unique advantages

  • Remains stable for a minimum of 1 year for 1.3 µS/cm and up to 3 years for all other values
  • Certificate with calibration document form DFM (available at www.hamiltoncompany.com)

  • Expiration date shown on every bottle

  • Bottles are permitted to stay open for a total of 60 minutes
