Conductivity Standard

For calibration of Conductivity (EC) meters in hydroponics

With Flairform’s analytical solutions, my tools are going an extra week between calibrations!


Regular calibration of conductivity meters is essential to ensure accurate readings.

bullet Flairform’s standard calibrates to 2.76mS/cm** (cF 27.6) at 25oC / 77oF.
bullet Formulated with NIST specified ingredients.
bullet Stabilised to resist algae or growth formation: ‘Growths’ can contaminate electrodes and cause interference that ‘distorts’ electrode calibration.
bullet Available in 250ml and 1L.

**Conversion chart:  For converting EC values to “ppm” for Hanna, Truncheon or Eutech TDS meters.

Important: Poorly maintained electrodes can upset the linearity (i.e. ‘slope’) of the readout values either side of the Conductivity Standard’s value. Thus it is essential to clean the electrode with Electrode Cleaner prior to calibrating.
