Explosion-proof dust sampler Explosion-proof dust sampler is widely used in environmental health monitoring, occupational health monitoring, industrial and mining enterprises, scientific research workplaces, etc. to collect the actual dust exposure in the workplace and the dust concentration of the workplace. The instrument is designed according to MT162-95 "General Technical Conditions of Dust Sampler in Workplace", Q / FY-02-2005 Enterprise Standard for Dust Sampler and Exib grade (intrinsically safe) explosion-proof design in GB3836.2000 standard. The dust pre-catcher can separate the respirable dust and coarse powder dust that are harmful to the human body, and its separation efficiency conforms to the internationally recognized "BMRC" curve standard. The instrument adopts the latest microcomputer chip control technology, built-in high-energy nickel-cadmium rechargeable battery, continuous operation time can be charged up to 8 hours at a time, simple operation, high timekeeping accuracy, ruggedness, convenient and fast time selection, countdown 0 to 99 hours 59 minutes Arbitrarily selected, the power is automatically turned off when the machine is stopped. It is an ideal sampler among similar instruments in China.
The dust sampler is composed of high-performance suction pump, microcomputer time control, battery voltage display, flow adjustment, automatic feedback constant current, and is also equipped with a variety of dust pre-collectors. Among them, a full dust pre-collector for measuring the total dust concentration; another impact pre-collector for measuring the concentration of respirable dust. For separation of dust, it can collect both breathable and non-breathable dust samples at once, and its separation efficiency reaches the internationally recognized "BMRC" curve standard. It is a more reliable and practical dust pre-separation device.
The instrument has small size, light weight, easy to carry, high timekeeping accuracy, accurate measurement, stable flow, and easy operation.
