one, product description

This product is one or four kinds of harmful gases in the air at the same time sampling instruments. For environmental monitoring, health and epidemic prevention, occupational diseases
Prevention, mining harmful gas collection, the determination of the room environment, tertiary institutions teaching, research and other units of the air of various harmful gases mining
Since the launch of the market, by the user pro-Lai.

Utility model patent (patent number: ZL 2010 2 0137402.3)

two, Features

1.The instrument is operated by four suction pumps alone.

2.Can be collected at the same time four different samples of harmful gases can also be collected from the balance of samples and four different time samples.
