Conductivity standards
Conductivity standards with stability of ±1% - guaranteed over a lifetime of up to three years.
- 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 from DFM
- Expiration date shown on every bottle
- Bottles are permitted to stay open for a total of 60 minutes
The procedure for determining conductivity was developed in collaboration with DFM (Danish Institute of Fundamental metrology). A representative number of bottles from every batch are measured by DFM. Their value is recorded on the calibration certificate and on every bottle. DFM enjoys the highest prestige in Europe in the area of electrolytic conductivity and is equipped with an absolute measurement cell that was developed in collaboration with NIST, and is accredited by the Danish accreditation agency DANAK to a conductivity of 0,9 μs/cm.
