Forbes Marshall offers conductivity standards with different conductivity values, whose stability of ±1% is guaranteed over a life cycle of up to 3 years. These standards can be used several times, on condition that the bottle is not left open (without its lid) for more than 1 hour in total. In order to ensure the accuracy of the conductivity standards, a representative number of bottles from each batch is measured by DFM. The DFM value is recorded on the calibration certificate and on each bottle.

• Features

  • Stable for at least 1 year (1.3 µS/cm), up to 3 years
  • Certified standards with traceable calibration from DFM
  • Expiration date on every bottle.
  • Bottles can remain open for up to 60 minutes and retain the certified value Stable for at least 1 year
