Overview
The DS-21BI dual path full dust sampler uses patch technology to replace traditional plug-in circuits and can perform parallel sampling. The parallel sampling distance is 10cm, which meets the standard requirements for air sampling. The characteristics of this instrument are high flow rate and stability, which can be used to collect total dust and inhalable dust. This instrument has functions such as timed control, time display, and battery voltage monitoring, making it easy to use and reliable. This sampler can be widely used for air quality monitoring in industries such as metallurgy, mining, petrochemicals, and building materials.

Product Introduction
DS-21BI dual path full dust sampler利用SMT technology replaces traditional plug-in circuits and allows for parallel sampling. The parallel sampling distance is10cm， Meets the standard requirements for air sampling. The characteristics of this instrument are high flow rate and stability, which can be used to collect total dust and inhalable dust. This instrument has functions such as timed control, time display, and battery voltage monitoring, making it easy to use and reliable. This sampler can be widely used for air quality monitoring in industries such as metallurgy, mining, petrochemicals, and building materials.
working principle
The sampler consists of a sampling head, flow meter, suction pump, and control circuit. The dust in the air is captured by the dust filter membrane under the action of the suction pump. The flow meter and timer set the sampling flow rate and time, and the weight gain of the filter membrane is measured by a balance to calculate the dust concentration.
