1、 Product Description

It consists of a high-performance suction pump, microcomputer time control, battery voltage display, flow regulation, automatic feedback constant current, and is also equipped with various dust pre collectors. The total dust pre collector is used to measure the total dust concentration; Another type of impact pre collector is used to determine the concentration of respiratory dust. This pre collector can separate respiratory dust and non respiratory dust that are harmful to the human body, and can collect both respiratory and non respiratory dust samples at once. This instrument has the advantages of small size, light weight, easy portability, high timing accuracy, accurate measurement, stable flow rate, and simple operation. It is mainly suitable for measuring respiratory dust and total dust in workplaces such as labor hygiene, environmental hygiene, and workshop air. Standard 6600 ampere hour lithium electrical appliances to meet long-term sampling requirements.
