Can the concentration of negative ions released by K-lon nano glasses be tested? How to test it?

The concentration of negative ions released by K-lon nano glasses can be detected, which requires the use of a professional negative ion detector. When operating, first make sure that the detector is in a calibrated state and has sufficient power. Place the detector's detection probe close to the surface of the glasses lens. The distance is generally controlled at about 10-20 cm, which is a more appropriate range for detecting the concentration of negative ions around the glasses. After turning on the detector, it will quickly capture negative ions in the air and present the concentration of negative ions near the glasses in the current environment in numerical form on the display screen, usually in units of /cm³. Generally speaking, when K-lon nano glasses are worn normally, the concentration of surrounding negative ions can be maintained at between several hundred and thousands per cubic centimeter. The product manual usually indicates a rough range of normal use concentrations, and the values ​​obtained by consumers' tests within this range can be considered to be in normal working condition.
