Description
Overview
GAOTek environmental negative oxygen ion tester is a high precision and professional instrument for detecting and analyzing air negative ions, formaldehyde, 2.5 pm, 10 pm, and air temperature and humidity. Adopting advanced cylindrical capacitor structure negative (oxygen) ion capture mechanism, the negative (oxygen) ions contained in the atmosphere are captured, and then precise statistical calculations are carried out through a unique algorithm. 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 size negative ions, with superior overall performance. It is easy to operate, with  full colour large screen displaying real-time measurement data, instrument working status, and automatic calculation of average values. Operators with zero foundation can quickly measure without professional training.
