Bluelab's 2.77EC Conductivity Solution, pH 7.0 and pH 4.0 Calibration Solutions are now available in 20ml sachets. pH measuring equipment must be cleaned and calibrated regularly t o ensure they are giving the user accurate readings. pH instruments are calibrated to pH 7.0 first (buffer) then to pH 4.0 (slope). The 2.77EC Conductivity solution is used as a reference or checking solution to ensure you have adequately cleaned the EC/CF probe. Calibration Solutions should be stored in a cool place out of direct sun and heat. Please keep out of reach of children. They should be stored with the lids securely tightened. Show more
