купить Калибровочные растворы для pH и TDS-метров

We offer high quality solutions for calibrating, adjusting and verifying pH and TDS meter measurements.Instruments typically need to be adjusted from several times a month to several times a year, depending on the quality of the instrument. If the devices are not checked in a timely manner, then all measurements by the devices are incorrect, inaccurate and in most cases even harmful. What can lead to the fact that all your work and efforts in an instantwill be corrupted.

This chemical reagent is able to maintain a certain pH to a certain level, depending on the specific amount of aggressive media, alkalis and acids. Each buffer mixture has a certain buffer capacity - the equivalent ratio of the number of alkali and acid elements.

Store buffer solutions in a cool, dark place (not in a refrigerator and at a temperature not exceeding 25°C) away from direct sunlight to prevent photochemical degradation. In addition, buffer calibration solutions must be protected from carbon dioxide from the air and stored in tightly closed containers.
