A pH adjuster is a chemical used to alter the pH or Potential Hydrogen level. pH (Potential Hydrogen) is the measurement of the activity of the hydrogen ion or how basic ,or acidic, something is. By adding a pH reagent such as an acid you can drive pH downward. By using a caustic or other ,alkaline, substance you can drive pH upward.

The ,alkaline, pH buffers are much more temperature sensitive and generally unstable as compared to the neutral ,or acidic, pH buffer. Many factors are the cause of this but the result is the same. If you have only two pH buffers employed (two-point single slope calibration) and one of the two buffers used is likely to be inaccurate this makes for a very poor calibration.
