To obtain precise and valid measurements, the pH meter and pH electrode must be calibrated at a minimum of 2 different points, close to the value of the sample to be tested. Hanna instruments offers a complete range of pH buffer solutions that will satisfy all your calibration needs. These solutions have been prepared for all those applications that require very accurate ph monitoring, and are also available with certificates of analysis prepared by comparison against the NIST standards. Available in packs of 10 x 20 mL and 25 x 20 mL.
