Gas pollutant generator

1、 Introduction

According to the national standard GB18801-2008 (and subsequent revised versions), when air purifiers undergo CADR (Clean Air Volume) testing for gas pollutants in standard cabins, they need to generate a certain concentration of pollutants in the cabin through corresponding pollutant generators (formaldehyde, benzene, toluene, etc.). The traditional method of occurrence is difficult to accurately quantify the occurrence of pollutants, and the initial concentration of different batches of testing cannot be controlled, resulting in certain deviations. This pollutant generator is capable of accurately measuring and generating pollutants, providing a constant and stable supply to the testing chamber, and is continuously controllable, ensuring the consistency of CADR testing conditions. The new version of the test cabin system is using this constant current pollutant generator and will gradually become a trend.
