Air Negative Ion Tester -ONETEST-502XP-Ⅱ It Can Measure Small Particle Sizes
1.Product brief introduction
ONETEST-502XP-Ⅱ Air negative ion tester adopts coaxial cylinder electrode design, with the advantages of stable sampling airflow, uniform ion distribution measurement and strong anti-interference ability. It can accurately measure the positive and negative ions from the small particle size in the natural air and the high concentration of negative ion generator and its products, and show the grade of air quality, which is used to measure the air quality more comprehensively. This instrument has built-in large-capacity charging battery and DC12V power adapter, which can be used for outdoor long-time measurement, and optional ion.onetestinc.com Cloud platform monitoring service, used for monitoring and transmission anytime and anywhere.

4, ECO instrument air rating
In general, the air freshness level is determined according to the number of suspended particles in the unit air volume. Our company adopts a more professional and more accurate judgment method- -the amount of negative oxygen ions in the unit air volume to determine the air freshness grade. When the negative oxygen ions content in the air is 1000-1500 cells / cm³, it is clean air. It can be seen that the content of negative oxygen ions in the air is an important standard to measure whether the air is clean. The following is the grade standard for ECO. Grade 1-6.
