Optional equipment | electronic measurement of pH

descon® test plus with electronic pH measurement | Corresponds to the requirements of DIN 19643 / November 2012.

Extract of the standard:
This fixed electrode must also be checked daily by means of an electrometric pH measurement (portable measuring instrument). Deviations between the continuous display unit and the control device must not exceed ± 0.2 pH units while maintaining the values stated in section 5.3, table 2 below. The electrometric pH measurement must be adjusted as two-point calibration according to the instructions of the manufacturer as regards frequency and sequence. It is mandatory that storage conditions for buffer solutions as well as their durability and purity are observed.
