KN-02 Air Purification Detector Product Description:

The KN-02 air purification dust detector is designed to measure dust per unit volume at the inlet and outlet of air purifiers

A handheld instrument that calculates efficiency based on the number of particles and dust particles at the inlet and outlet.

The air purification detector is the basis for our company to introduce advanced high-sensitivity microsensor technology from abroad

Based on the independently developed aerodynamics, digital signal processing, opto mechatronics integration, and formaldehyde

High tech products for testing.

This detector can simultaneously detect dust particles in two particle size ranges at an air sampling flow rate of 1 liter/minute

Detection and separate measurement of formaldehyde. It has high measurement accuracy, stable performance, strong functionality, and small size,

The characteristics of simple and convenient operation have reached or exceeded the performance indicators of similar international products. It can be wide

Widely applied indoor and outdoor environment detection, effectively reflecting the number of dust particles and formaldehyde in the current environment

Concentration value; At the same time, the purification efficiency of the air purifier can be reflected in real-time. Therefore, also

Very suitable for testing the purification effect of air purifiers. This instrument uses the electrochemical sensor method

The electrochemical sensor method is based on the principle of electrochemical reaction, that is, the instrument uses a voltage type sensor to

Work under controlled diffusion conditions. When gas molecules are absorbed into the electrochemically sensitive electrode,

After passing through a diffusion medium, gas molecules undergo electrochemical reactions at an appropriate sensitive electrode potential,

Generate a current proportional to the gas concentration, which is converted into a voltage value and transmitted to the instrument

Meter reading or recording.
