CCHG1000 direct-reading instrument measuring dust concentration in real-time monitoring of the concentration of dust in the workshop

CCHG1000 direct-reading dust concentration measuring instrument Introduction: CCHG1000 direct-reading dust concentration measuring instrument with infrared light absorption principle method, the measuring device floating in the air dust concentration. The apparatus according to MT163-1997 "direct-reading dust concentration measuring instruments General technical conditions" and Q / 320581FYK007 "CCHG1000 direct-reading dust concentration measuring instrument" corporate standards and GB3836.4-2000 standard Exibl grade (this cause safety) proof design dust concentration measurement instruments. Dust concentration tester Hu suction separation means separation efficiency entirely consistent with internationally recognized "BMRC" profile requirements, accurate and timely reflection of personnel exposed to dust inhalation Hu suck dust and pollution of different quality dust dust in the workplace, as accurate evaluation of workplace health provide reliable data. For a coal mine explosion in workplaces and qit2 contain dangerous gases. The instrument is compact, simple to operate, load, high vacuum capability, automatic timed sampling, flow stability, the whole Chinese liquid crystal display, easy to carry and so on. CCHG1000 direct-reading dust concentration measuring instrument technical indicators: 1, the dust concentration measurement range: 0.1mg / m3-1000 mg / m3 2, dust concentration measurement relative error: ± 20% 3, stability relative error: ± 2.5% 4, Sampling flow: 2.0L / min 5, sampling flow error: ≤2.5% 6, sampling flow stability: ≤ ± 5% 7, sampling Performance: meet the "BMRC" sampling effectiveness curve 8, Power supply: Ni-H batteries 2.5A / h, 6 9, the working voltage: 6.5 V-8.4 V Dc (intrinsically safe) 10, explosion-proof type: Mine intrinsically safe, explosion-proof mark: Exibl 11, direct-reading dust concentration (mg / m3) 12, there PM10, PM2.5 and TSP cutter to choose from a variety of 13, with a 40mm filter sampler, the instrument can be collected at the same time continuously detect dust sample 14, and data acquisition module is connected to the wireless transmission and remote monitoring for continuous detection of 15, with a labor health model, can be obtained TWA and STEL 16, using powerful suction pump, is more suitable to be equipped with central air conditioning vent a longer sample tubes PM10 respirable particulate matter concentration detection 17, the detection sensitivity can be up: 0.001 mg / m3, the maximum detection limit: 1000 mg / m3 18, Dimensions: 280 × 228 × 80 (mm) 19, Quality: 3.0Kg
