The frequency of calibration ultimately depends on how accurate you like your numbers. Daily calibration is ideal; however, we get that calibration takes some extra time out of what might be a busy schedule.

WebbAcidic solutions have a pH value lower than 7, and basic or alkaline solutions have a pH level higher than 7. Blood, which is over 90% water, is normally slightly basic, with a normal pH range of about 7.35 to 7.45. Usually, your body maintains the pH of … WebbYes, pH and conductivity are related, but not linearly or in an absolute manner. A pH sensor responds solely to H + in a solution, whereas in conductivity the sensors measure the activity of all charged ions (anions and cations) present in a solution. The higher the concentration of ions, the higher the conductivity.

A solution with a pH between 5 and 7 is neutral, 8 or higher is a base, and 4 or lower is an acid. For more detailed information, consult the Science …
WebbStrong acids have a high percentage of their atoms found as ions (ie unbound), whereas weak acids have only a low percentage of ions in solution. The pH scale ranges from 0 to 14 in water. The closer to 0, the stronger the acid, whereas the closer to 14, the stronger the base. A pH of 7 is neutral, or neither basic nor acidic.
WebbMost organisms, including humans, need to maintain pH within a fairly narrow range in order to survive.
