Bluelab® pH 4.0 Calibration Solution 500ml Co2 Tanks whiteflies andpH measuring equipment must be cleaned and calibrated regularly to ensure they are giving the user accurate readings. pH instruments are calibrated 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 solution to ensure you have adequately cleaned the EC CF probe.
