Moisture meter Electrochemical cell introduction

  Gently shake the electrolytic cell of the trace Moisture Meter a few times to make the water on the inner wall of the cell bottle fully absorbed by the electrolyte, then put the electrolytic cell into the holder, turn on the stirring switch, adjust the stirring speed, and make the liquid surface form Make a small vortex; insert the measuring electrode plug and the electrolytic electrode plug into the corresponding socket of the host, and make them in good contact, and turn on the electrolytic switch.

If the electrolytic cell is still in a deep iodine state, use a 50ul micro-injector to extract 10ul of distilled water each time, wipe the needle with filter paper, press the start button, and inject it into the liquid surface of the electrolytic cell through the hole in the middle of the sampling cock several times. Next, inject at any time and observe the color change of the electrolyte at any time until the electrolyte turns light yellow, the green light of the measurement signal light and the electrolysis signal light indicate, and the counter starts counting.

After the electrolyte is stable, use a 0.5ul micro-sampler to extract 0.3ul of distilled water, wipe the needle with filter paper, press the start button, inject it below the liquid level, the instrument will start counting, and when it reaches the end point, it will display 300±30ug of water, continuously calibrate for 2~ 3 times, the counting values ​​are all within the required range, indicating that the instrument is accurate.
