Comparison and characteristics of negative ion detector equipment on the market
At present, the common negative ion detectors on the market are basically two kinds of parallel electrode plates and capacitor methods. On the basis of these two test principles, different types of negative ion detectors are derived.
The principle of the negative ion tester using the parallel electrode plate test is generally not good to solve the effects of static electricity and external airflow, but it occupies the advantage in production cost. The instrument price is more advantageous. Although there is a certain drift, it can basically be judged. The concentration of positive and negative ions.
At present, relatively good air anion detectors on the market are commonly used as handheld anion detectors using the principle of parallel electrodes, such as the United States: AIC1000 anion detector, AIC2000 anion detector; Japan KEC900 anion detector, KEC990 anion detector . But the drift rate is still relatively high, almost Â± 25%.
Negative ion tester There is another kind of negative ion tester is the capacitor method. The detection principle of the capacitor method is more advanced. It can solve the influence of airflow and static electricity through a cylinder, and it is more convenient to clear, but it is sold on the market. Are very expensive. For example, COM3800 negative ion detector, COM3400 negative ion detector, and COM3600 negative ion detector basically adopt this detection method.
At present, there is a new TZRH-3200PRO negative ion detector on the market, which adopts the capacitor method, with data analysis software, and can be directly connected to the computer. It is the first choice for environmental detection stations and tourist attractions. ()
TZRH-3200PRO high precision economical air ion tester
Features: The detector is designed and manufactured according to the most accurate coaxial double-cylinder type in the draft of the JIS Ion Density Determination Method. Compared with the flat-type ion detector on the market, the accuracy is greatly improved And can use special computer record analysis software to record analysis and print the measured data, suitable for assessment of living environment and detection of the same commodity.
