Page 14: Operating Procedures
3 OPERATING PROCEDURES 3.1 PRINCIPLE OF MEASUREMENT The new patented 9091C Dissolved Hydrogen Analyzer electrochemical hydrogen sensor functions in a potentiostatic mode with an open three-electrode system. The measuring electrode is made of solid titanium, coated with platinum. The counter electrode is made of stainless steel and the reference electrode of silver/silverchloride. -
Page 15: Calibration Via Electrolysis
3.2 CALIBRATION VIA ELECTROLYSIS The calibration cell contains two stainless steel electrodes, between which water is dissociated by a constant, controlled, current. According to Faraday’s law the rate of hydrogen production in the calibration cell is directly proportional to the current. A constant electric current of 13.4 mA, for example, produces an increase in the hydrogen concentration of 50 µg/l at a flow rate of 10 l/h. -

Page 18: Preparing To Measure
4.2 PREPARING TO MEASURE Before you start measuring you my perform the following procedures. 1. The electrical power supply has to be connected according to the local power authority guidelines with the terminal box, with witch the connectors to the 0(4)...20 mA analog output (see the circuit diagram on the cover plate) should be combined. - Page 19 > and AutoCal >. (option only). With the key you can go ahead. With the key will release the electrolytic calibration if you start from position ElyseCal >. From SubCal > you are setting the present hydrogen concentration digit for digit, finally push key SET.

Page 20: Measuring Mode
5 MEASURING MODE 5.1 OPERATING CONDITIONS For an accurate measurement of hydrogen the probe’s environment must fulfill certain conditions regarding conductivity, flow, temperature and pressure. The probe conductivity must be 10 µS/cm; otherwise the salt cell must be refilled (see also Section 4.2). ... -

2) If you selected the calibration mode SubstCal > in the CalModus : You start the calibration procedure by pressing key (suitable for Hydrogen measuring). The display changes to: SubCal 000.0 μg/l The setting of the present hydrogen concentration is performed digit for digit. If the value is correct, press key SET. -
Page 22: Cleaning Of Cells
6.2 CLEANING OF CELLS The cleaning cycle of both the counter electrodes of the measuring and calibration cells is the same as those of the measuring electrode and calibration electrode. To clean the counter electrodes, you close the inlet valve and remove the plug connectors (A), (K) for the calibration cell, as well as (M), (C) and (R) for the measuring cell. -
Page 23: Spare Parts And Accessories
If you observe unsteady or unlikely results during the measurements, check if the plug connectors are dry and make sure that the reference electrode is completely immersed into the KCl-solution. During longer periods, where no measurement a takes place, (for example longer than 3 weeks) it is advisable to clean the analyzer.
