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