Brief introduction: Mining, metallurgy, chemical manufacturing, the centers for disease control and prevention, health supervision, safety bureau, ring stand, on-line monitoring, emergency detection. The instrument adopts the advanced technology for central processing unit (CPU). To collect various data processing is fast, strong anti-jamming capability, greatly improving the detection precision of the instrument, at the same time can on time sequence stored 50 times test records. Chinese instruments by display, high performance pump, dust concentration detection circuit, under-voltage protection, according to the safe power supply, etc. The instrument is equipped with graded dust catcher, can collect the respirable dust concentration, its separation efficiency in accordance with internationally recognized standard "BMRC" curve. Instrument can adopt the way of automatic sampling or manual sampling, to adapt to the different test standards. The instrument adopts the ExibI (150 ℃) level safe explosion-proof structure, especially suitable for the coal mine and other workplaces use containing explosive dangerous gas. Technical indicators: 1. Meter dust concentration measurement range: 0-1000 mg/m3 2. The apparatus dust concentration measurement error is: < 10% 3. The relative error tester stability: plus or minus 2.5% 4. Sampling scope: dust, dust 5. Sampling flow for: 2 l/min 6. Sampling flow error: < 2.5% 7. Appearance size: 220 mm * 150 mm * 82 mm 8. Instrument weight: 1.5 kg
