Basic knowledge points of trace moisture analyzer
Micro moisture testers are widely used in fields such as electricity, petroleum, chemical pharmaceuticals, food, and solar panel cutting fluids. Today, Shanghai Danding will explain to you the basic knowledge and key points of a micro moisture analyzer. The following mainly introduces the characteristics of the micro moisture analyzer, preparation before use, as well as common problems, causes, and solutions:
Characteristics of trace moisture analyzer
Small size and light weight; Equipped with Chinese display of titration process, capable of input and output in both Chinese and English.
Color LCD screen display, graphical interface, simple and convenient operation, easy to master.
The LCD screen directly displays dew point, micro water (ppm), environmental temperature, environmental humidity, time and date, battery level, and other contents.
Touch screen input allows for independent completion of complex detection processes with just a few clicks.
Preparation before use
1、 Handling the electrolytic cell: Specific operation: Gently shake the electrolytic cell a few times to fully absorb the water on the inner wall of the cell bottle by the electrolyte. Then, place the electrolytic cell in the holder, turn on the stirring switch, adjust the stirring speed, and form a small vortex on the liquid surface. Insert the measuring electrode plug and electrolytic electrode plug into the corresponding socket of the host, and make good contact. Turn on the electrolytic switch.
Note: In the state of excessive iodine, the green lights of the measurement signal indicator light and the electrolysis signal indicator light are all turned off, only one red light is lit separately, and the digital display does not count.
2、 Adjust the balance of the electrolyte: Specific operation: If the electrolytic cell is still in a deep iodine excess state, press the start button and inject multiple times below the liquid level of the electrolytic cell through the hole in the middle of the injection cock. Inject at any time and observe the color change of the electrolyte until it turns light yellow. The green light of the measurement signal light and electrolytic signal light indicates that the counter starts counting. After the counting stops, stop stirring again, pick up the electrolytic cell and gently shake it a few times to absorb the water on the inner wall of the bottle again. After the endpoint alarm is triggered, calibration can be carried out.
3、 Calibration: Specific operation: After the electrolyte is stable, use a micro sampler to extract a small amount of distilled water, wipe the needle with filter paper, press the start button, and inject it below the liquid level. The instrument starts counting, reaches the endpoint, displays the water volume, and continuously calibrates 2-3 times. The counting values are within the required range, indicating that the instrument is accurate.
Explanation: When using distilled water (100%) for calibration, the allowable error is within ± 10%.
