How to use HK-51 Benchtop Sodium Meter | Operate | Measure Sodium ion in Water Sample of Power Plant

HK-51 Benchtop Sodium Meter is the latest laboratory instrument developed by Beijing Huakeyi Power Plant Instrument Research Institute, is a very important instrument for a Coal Fired Thermal Power PLant. HK-51 Benchtop Sodium Meter is consisted of the meter, sodium electrode, reference electrode, ATC temperature electrode and the electrode holder. It adopts the high sensible electrode system to make sure the stability and accuracy of sodium measurement. The meter has one temperature input channel. When automatic temperature compensation is needed, the sample temperature can be measured by a Pt1000 thermometer, otherwise manual temperature compensation will replace the automatic temperature compensation. The effect of the sodium concentration variation to the electric potential of the sodium electrode can be depicted by the Nernst equation. The equation had indicated that, the measured electric potential will variate with the variation of the temperature and the related ion concentration. In order to eliminate the errors caused by the water temperature variation, HK-51 sodium meter will amend the temperature compensation value timely according to the temperature measured by the ATC temperature electrode.
