。 The negative (oxygen) ion capture mechanism of cylindrical capacitance structure is used to capture the negative (oxygen) ions contained in the atmosphere, and then accurate statistical calculations
are carried out through the algorithm.
It has the advantages of
stable measurement process, rapid response and accurate measurement results.
At the same time, it has strong anti-electromagnetic, static and electromagnetic wave interference capabilities, sensitivity and capture ability to small particle size negative ions, and the overall performance is superior
.
Working principle: The principle of "capacitive inhalation method" is used for negative ion detection and measurement of negative ion concentration in
the air.
A quantitative polarization voltage is loaded on the polarization plate (or bias plate) of the ion sensor (or collection barrel, collection cylinder), and then the measured air passes through the sensor
at a uniform speed at a set speed.
Specific small particle size negative ions in the air are deflected by the electric field and are captured
by the collection plate.
The amount of negative ion negative charge collected is processed by the collector to calculate the charge concentration value
of the negative ion.
