Negative oxygen ion detector recommended

Negative oxygen ion detector is a handheld detection of negative oxygen ion instrument, high precision, professional, with a 5-inch color screen, real-time display of measurement data, instrument working status, and automatically calculate the average value. The operation process of this equipment is very simple, and zero foundation can be used without training.
Model: FT-FY1
Brand: Fengtu

Product size: 200mm*132mm*58mm
Weight: 1kg
Function description: Suitable for hospitals, schools, families and other places to quickly monitor the concentration of negative ions in the air, and can feedback the results to managers and staff, in order to make timely adjustments to improve the air quality level.

The negative oxygen ion detector is precise, compact, portable, and has good stability and durability. It uses lithium battery charging, responsive, data refresh frequency of 1 second/time. The measuring principle is based on the internationally common cylindrical capacitive suction method. The negative (oxygen) ions contained in the atmosphere are captured by the negative (oxygen) ion trapping mechanism of the cylindrical capacitor structure, and then accurate statistical calculation is carried out by the unique algorithm.
