Bluelab® pH 4.0 Calibration Solution
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.
