"This instrument is a measuring device that continuously measures the concentration of ions in the air and quantifies the number of molecular ions known as 'small ions'."Small typeYes.

Unlike simple instruments that can only measure low concentrations, "High concentration」「 High precision"achieved"Authentic Ion Counter"It will turn out like this."

JIS standard (B9929) certified "The Gordian KnotUsing "measurement method"5,000万个/mm3 ]It can be measured.

Additionally,Function for measurement correction based on air volume.Equipped with "More precise value"It can be quantified. 'It should have better performance... to prevent "underestimation" or overestimation that could "exceed the original value and damage credibility."'"
