CCZ20 dust sampler Lu Heng Electric our core values: commitment to allow customers to enjoy the widest range of the highest quality products and services, customers become the most trusted partner to expand Industry, China's electrical industry model. CCZ20 mine dust sampling instruments with or without pulsing air, vacuum, load capacity, automatic timed sampling, safe, reliable, durable, easy to carry and use in the field and so on. CCZ20 mine dust sampler consists of high performance suction pump, automatic time control circuit, flow regulator circuit, automatic constant current feedback circuit, undervoltage alarm circuit protection, safety power supply, etc., comes with a variety of pre-trap dust. CCZ20 mine dust sampler Features CCZ20 type mine explosion dust sampler is an instrument for measuring the ambient concentration of dust floating in the air. For a coal mine and other workplace containing gas explosion hazard. The dust sampler is equipped with two kinds of pre-trap, one is measuring the concentration of total dust full dust pre-trap, the other is the determination of the concentration of respirable dust pre-trap, such pre-trap can for respirable dust hazards to human and non-respirable dust separation, a collection can have both respiratory and non-respiratory two dust samples, the separation efficiency to achieve the internationally recognized: "BMRC" standard curve, is a more reliable The dust separation device. The instrument is also equipped with a high performance aspirator pulseless flow, load, large negative capability, automatic timed sampling, flow stability, simple operation, easy to carry and so on. CCZ20 mine dust when using parameters respirable dust sampler: When 20L / min (flow) total dust: 25L / min (flow) Load capacity:> 300Pa flow sampling error: ≤2.5% Timing range: 0-99 minutes arbitrarily set Continuous working time:> 120min Working noise: ≤70 Working Power: 6 2.5A / h (Ni-H) Battery Rated voltage: 7.2V Dimensions: 200 × 120 × 75 (mm) Weight: ≤1.75㎏ proof in the form: Mine intrinsically safe explosion-proof mark: Exibl our values: customer first, teamwork, professional dedication, innovation, positive action, forever young, brave and bare our team: integrity is the foundation to a passion for the vitality and diligence for wisdom, professional core, innovation-driven economy Ninglu Heng Electric Equipment Co., landline: 0537-2080758 Fax: 0537-2585538 phone: 15965728997 QQ: 3179595347 Contact: Feng Yang
