The pH4 solution is a high-quality calibration buffer for calibrating your pH sensor. It allows you to give your electronic tester a second reference value before use. It can therefore be used to readjust the measurement of your water so that it is accurate. It compares the measured value with this known reference solution, thus serving as a precise reference for the slope between pH7 and pH4. The sachet indicates the solution’s reference pH level as a function of the solution temperature during calibration. The expiry date is stamped on the sachet.<\/p>\n
