Negative ion tester product introduction:

Negative ion tester is a high-precision, professional air negative ion and formaldehyde detection and analysis instrument. It adopts an advanced cylindrical capacitor structure negative (oxygen) ion capture mechanism to capture negative (oxygen) ions in the atmosphere, and then uses a unique algorithm to perform precise statistical calculations. It has the advantages of stable measurement process, rapid response, and accurate measurement results. At the same time, it has strong resistance to electromagnetic, static electricity, and electromagnetic wave interference, and has excellent sensitivity and capture ability for small-particle negative ions, with excellent overall performance.

The negative ion tester is easy to operate, with a 5.0-inch full-color large screen that displays real-time measurement data, instrument working status, and automatically calculates the average value. Operators can quickly measure without professional training.

Negative ion tester product application:

It can measure the concentration of atmospheric negative oxygen ions and formaldehyde in the air in real time. It is an optimal tool for measuring and demonstrating the concentration of negative ions in environmental monitoring, nano-coatings, negative ion health products, negative ion home improvement building materials, indoor testing, air treatment, air purifiers and their products.

Negative ion tester working principle:

The principle of "capacitive inhalation method" is used to detect negative ions and measure the concentration of negative ions in the air. A certain amount of polarization voltage is loaded on the polarization plate (or bias plate) of the ion sensor (or collection barrel, collection tube), and the air to be measured passes through the sensor at a set speed. Specific small-particle negative ions in the air are deflected under the action of the electric field and captured by the collection plate. The negative charge of the collected negative ions is processed by the collector to calculate the charge concentration of the negative ions.
