ETF-30D dust sampler Introduction: This sampler is widely used in atmospheric environment monitoring. Hygienic and epidemic prevention, labor protection, scientific research, teaching and other units are used to measure the concentration of workplaces containing dust hazards. Analyze the sampled gas to understand the degree of pollution of the environment by harmful gases. The instrument is compact in structure, stable in performance, small in size, light in weight, and easy to carry. It is currently the most ideal instrument among small portable atmospheric sampling instruments in China. The instrument is mainly composed of a two-way suction pump, a regulating valve, a flow meter, a sampling head, a timing circuit, a charging circuit, and a power supply circuit. The dust concentration of this instrument is measured by collecting fiber-containing air with a fiber filter membrane of known mass, and the dust concentration in the unit volume of air is determined from the increment of the filter membrane after sampling. Sampler uses: indoor air quality; efficiency studies of filters and clean rooms; labor hygiene; environmental monitoring technical parameter 1: Microcomputer timing control, AC and DC dual-use 2: Rated load flow: 5-30L/min 3: Negative suction pressure: ≥15000pa 4: Flow accuracy: level 2.5 5: Continuous working time: ≥180 min 6: Volume: 213×133×150mm3 7: Weight: 3.2 kg 8: Working voltage: AC 220V or DC 10V (8 rechargeable battery packs)
