Measuring method of material negative ion detector

Negative ion measurement mode: This mode is the result of calculating the negative ion value measured by the sensor.

1. Press the Power button, and the display will appear on the display. Second, after 20 seconds, the average value of negative ions per second for 20 seconds will be displayed. 3. When measuring again, press the Reset button to wait for the display to appear on the display. 4. After 20 seconds, the average value of negative ions per second for 20 seconds will be displayed. 5. After the measurement is completed, press the Power button. Negative ion detection mode: This mode is the result of directly displaying the negative ion value measured by the sensor. 1. Press the Reset button for more than two seconds to change the measurement mode to Mode2. Second, start measuring at the same time. The measured results are displayed directly during the measurement. 3. When measuring again, press the Reset button to wait for the display to appear on the display. 4. After the measurement is completed, press the Power button. The measuring device is mainly for measuring negative ions emitted from natural ores, ceramics and the like. Function: Measure products made from natural ores and ceramics: such as fabrics, bedding, clothing, wall materials, decorations and other products for management and promotion purposes. The measurement method is to use a high-sensitivity GM tube to measure the weak radiation generated from natural ore and ceramic and then calculate it as negative ions. It can also be used for the detection of ore, the detection of magic cushions, and the promotion of rock pot baths that are very popular today.
