The determination of moisture in the sample

Before determining the operation, the following points should be determined whether they are correct:

1. Be sure to enter the measurement interface. 2. Is the voltage at the lower left corner stable? 3. Mix at the right speed.

1. Determination of moisture in liquid samples

(1) First, the 1ml injector with a needle (other capacity syringes can be selected according to the different samples on the side) is rinsed with the tested sample for 2-3 times, and then a certain amount of samples is taken to prepare for the injection.

(2). Press the Start button to clear the display. Tip: Please inject the sample to be tested for measurement

(3). The sample through into the cock in the anode chamber into the electrolyte, the attention should make needlepoint inserted into the electrolyte, and avoid contact with the wall or electrode, the titration will automatically start after injection, the determination of the end, the buzzer sounded, state prompt normal, digital display shows is the sample water content, unit of ug. Water content is shown to the right of water content .

Note 1: In the process of measurement, due to the error of operation, such as late clicking the back button, it will return to the starting interface and the measurement will be terminated, so the correct data cannot be obtained. In this case, it is necessary to re-enter the measurement interface until the state becomes normal and the equilibrium voltage is stable.
