Explanation:
An electronic air sampler is a device that is used by people to check apprehension of contamination having individuals with the help of certain volume of air sampling.
The Device is used for recording the chemical data of contamination and the real-time data is sampled and recorded and the data is processed and stored. The air sampling is done in two ways.
