Flairform Calibration Solution Kit - pH Buffer 4.0 & 7.0 (250mL) water chillers & heaters This will ensure that itIntroducing the Flairform Calibration Solution Kit pH Buffer 4. 0 & 7. 0 pH meters must be regularly 'calibrated' (i. e. adjusted for accuracy) using standard pH buffer solutions which are made to an internationally agreed recipe. It is essential to calibrate using at least TWO pH buffers. These need to differ in pH by at least three pH units over the pH range being used. For nutrient solutions, pH buffer 4. 0 and 7. 0 are the ideal calibration
