I. Overview

The DWF-30E Constant Current Positionable Large Flow Dust Sampler, independently researched and produced by Yancheng Dewang Instrument Equipment Co., Ltd., is an instrument with patented technology capable of collecting total dust and respirable dust in the air. It is suitable for the sampling of fixed dust and metal dust particles of occupational hazards in the workplace; also applicable to routine and emergency monitoring of environmental air, public health, and occupational health.

The Constant-Current Positioning Large-Flow Dust Sampler is mainly composed of: operating system, intelligent control system, air pump, flow measurement system, and positioning data upload module. It can continuously operate for over 8 hours on a single charge, convenient for sampling tasks. The instrument features real-time display of flow rate, sampling volume, sampling time, temperature, atmospheric pressure, and battery level. It is compact in structure, small in size, light in weight, durable, has strong load-bearing capacity, stable and accurate flow rate, and low noise. It is portable for easy use during sampling.

Section II: Application Fields

The DWF-30E Constant-Current Positionable Large-Flow Dust Sampler is an ideal instrument for short-term or long-term air sampling by environmental protection personnel in disease prevention centers, environmental monitoring stations, colleges and universities, research institutions, and testing organizations.
