Bluelab Calibration and Conductivity Solution Sachets

Bluelab's 2.77EC Conductivity Solution, pH 7.0 and pH 4.0 Calibration Solutions are now available in 20ml sachets. Each sold separately. pH measuring equipment must be cleaned and calibrated regularly to 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.
