PH electrochemical electrode

ORPglassfor water

Combined pH and ORP electrodes are supplied with a protective cap, which is filled with a 3mol KCL solution. In this condition the electrodes can be stored max. 1 year. Therefore the protective cap should be removed only just before installation and use. 2.The shank of the combined electrode consists of glass and is easily fragile. At installation it must be ensured absolutely that the tube does not push anywhere. 3.Because the characteristics deviate from the ideal line, for the precise measurement it is necessary to calibrate the electrode after start-up and then in regular time intervals. 4.A combined electrode must not drain at the active tip, otherwise it becomes useless. To recover the active tip of the electrode it can be dipped for about 24 hours into a 3mol KCL storage solution. Subsequently, a calibration is necessary, because zero point and slope may have been drifted. 5.In dirty and containing protein media a cleaning of the electrodes is necessary occasionally. When using purpose we offer a special cleaning solution. After cleaning, the electrodes must be rinsed with water.
