Calibration and conductivity standard solutions... a must in every grower's toolbox. The Bluelab calibration and conductivity standard solutions are essential for use with all Bluelab products for the calibration of pH and testing the cleanliness of the Bluelab Conductivity/Temperature probe. Bluelab solutions are manufactured specifically for Bluelab products and are referenced to high laboratory standards to ensure your Bluelab products last longer and maintain accuracy. Bluelab's EC/CF equipment does not need calibrating as they are all factory calibrated here at Bluelab. The CF27.7 (EC2.77) solution is used as a reference or checking solution to ensure you have adequately cleaned the EC/CF probe. Contamination between solutions can easily occur, which will affect the validity of the calibration. Bluelab recommend that the solutions are de-cantered into a smaller vessel and the contents discarded when the calibration process has been completed.

  • PH instruments are calibrated to pH 7.0 first (buffer) then to pH 4.0 (slope)
  • Store in a cool place out of direct sun and heat
  • They should be stored with the lids securely tightened
  • Chart & PIPETTE INCLUDED WITH EVERY ORDER
  • Reference or checking solution to ensure you have adequately cleaned the EC/ppm probe
