pH measuring equipment must be cleaned and calibrated regularly to ensure they are giving the user accurate readings. pHæinstruments areæcalibrated to pH7.0 first (buffer)æthen to pH4.0 (slope). Bluelab's EC/CF equipment does not need calibrating as they are all factory calibrated. The CF27.7 (EC2.77)æsolution is used as a reference or checking solutionæto ensure you have adequately cleaned the EC/CF probe.
