How do customers choose negative ion detectors and purchase tips for negative ion detectors?
First of all, we must understand the use of negative ion detection. Currently, there are imported negative ion detectors , domestic negative ion detectors , counterfeit negative ion detectors, and so on. Divided into portable negative ion detector , online negative ion detector , according to the principle is divided into parallel electrode negative ion detector and circular pass capacitor negative ion detector .
So how do we choose our own negative ion detector .
In general, the portable negative ion detector is convenient for on-site inspection. For example, when detecting the indoor and outdoor air environment, the range is generally not too large, 10 to 2 million / cubic centimeter, and the negative ions of the natural environment are generally 100,000. / cubic centimeter. At present, the largest negative ions in the domestic natural environment are also below 50,000/cm3. Therefore, we have a spectrum in choosing the range. The portable negative ion detector can be selected from the American AIC2M negative ion detector , the Japanese KEC900 negative ion detector or the Japanese COM3200PRO II negative ion detector .
The accuracy of the general tact is slightly higher, but the reaction rate is slower. The parallel electrode method detects that the speed is faster, that is, the sensitivity is not as high as that of the parallel electrode plates. Parallel electrode plates are highly sensitive but have a strong impact on static electricity and the environment, while circular-pass capacitors have relatively small effects on static electricity and the environment, and each has its own advantages and disadvantages. The single price is still very different. Generally, the round-through capacitors are bought relatively high.
For the air purifier detection, there are currently two kinds of air circulatory physical adsorption method to remove dust and fine particles in the air, and the other is that the electrode method purifies the air by generating a large amount of negative ions. The latter method generally uses a negative ion detector, and the variety of air purifiers released by the negative ion effect is different. This requires a good negative ion detector for detection, based on how far the negative ion is from the air purifier to determine his air purification effect. Generally choose the US AIC20M air negative ion detector and the Japanese KEC990 air negative ion detector . Why should we choose parallel electrode plates? It should be said that the reaction speed of the parallel electrode plates is fast, the sensitivity is high, the electrostatic and environmental effects are generally evaded indoors, and their price is not particularly expensive.
High-power industrial grade negative ion generators are generally between 4-5 million and even hundreds of millions. How do you choose an negative ion detector ? At present, there can only be a US AIC200M negative ion detector with a range of 1000-200 million/cm3. It is currently the largest range of negative ion detectors on the market. It is also the industrial choice.
