KBM-110 Bases for measurement | 6 6 Bases for measurement 6.1 pH measurement 6.1.1 Explanation The pH value describes the acidic or alkaline behaviour of an aqueous solution. A pH value below 7 is acidic, a value above 7 is alkaline. A pH value of 7 is neutral. The pH measurement is very precise, but also sensitive. The measured signals are very weak and high-ohmic. This is the case, in particularly in low-ion media.
6 | Bases for measurement KBM-110 6.1.4 Further information A pH electrode is a wear part. If the signal is very slow or the required values are no longer observed after careful cleaning and possible regeneration, the electrode must be replaced. When using the electrodes, be aware that various substances in aqueous solutions can corrode glass and that chemicals can produce a chemical reaction with the KCl solution in the electrode, which can result in blockage of the diaphragm.
KBM-110 Bases for measurement | 6 6.1.7 Care and maintenance NOTE The GAK 1400 working and calibration set includes all necessary products for calibration, care and maintenance of the electrode. Normal cleaning takes place with the GRL 100 pepsin cleaning solution into which the electrode is immersed for 5 minutes before being rinsed off with clean water. NOTE Crystallisation of the 3 mol/l KCL solution is unavoidable.
7 | Maintenance KBM-110 7 Maintenance 7.1 Operating and maintenance notices NOTE The product and electrode must be handled with care and used in accordance with the technical data. Do not throw or strike. NOTE Plugs and sockets must be protected from soiling. NOTE If the product is stored at a temperature above 50 °C, or is not used for an extended period of time, the batteries must be removed. Leaks from the batteries are avoided as a result.
KBM-110 Maintenance | 7 – Only use high-quality and suitable alkaline batteries! CAUTION Damage! If the batteries have different charge levels, leaks and thus damage to the product can occur. – Use new, high-quality batteries! – Do not use different types of batteries! – Remove depleted batteries and dispose of them at a suitable collection point! NOTE Unnecessary screwing places the water-tightness of the product, among other things, at risk and should be avoided.
7 | Maintenance KBM-110 For automatic calibration, open the Calibration menu. See Automatic pH calibration [} p. 19]. Prerequisite – The pH electrode and, if applicable, a temperature sensor are inserted in the product. – The product is switched on. Instruction 1. Carefully remove the protective cap from the electrode. 2. Rinse off the electrode with distilled or deionised water. Outcome of an action Now, the product can be calibrated. 7.3.1.
