LD-3C (B) microcomputer laser dust monitor

LD-3C (B) microcomputer laser dust monitor main technical indicators: Detection sensitivity: LD-3C (L) 0.01mg / m3; LD-3C (H) 0.001 mg / m3; measuring range: LD-3C (L) 0.01 ~ 100 mg / m3; LD-3C (H) 0.001 ~ 10 mg / m3; Measuring time: sampling standard time of 1 minute, with a 0.1,1,2,5,10 minutes and manual transmission (random sampling time); repeatability error: ≤ ± 2%; Accuracy: ± 10% Display: 4 LCD display with logo; storage: 99 sets of data storage can be recycled; regular sampling: measuring time can be set from 1 to 9999 seconds and sampling frequency of 1 to 9999 output interface: PC machine communication interface (RS232) and printer output interface Ambient temperature: 0 ~ 40 ℃ (Storage temperature -20 ~ 60 ℃) Power: AC and DC, with a rechargeable battery and charger Size: 192 × 69 × 140 mm Weight: 1.4Kg II Introduction: the international advanced level of pocket fast dust analyzer, direct-reading dust concentration (mg / m3), 1 mins result. Determination of the air of respirable particulate matter (PM10) and respirable dust concentrations, total dust concentration of the instrument of choice, there are more than thousands of units in use around the country. LD-3C Laser Dust Monitor is the latest pocket dust Laser light source with the international advanced level. The only sector in line with the Ministry of Health standard instrument measuring dust quickly; there are more than thousands of units in use around the country. ? The introduction of Japan full set of manufacturing and testing equipment calibration technology and industry standards in line with the Ministry of Health WS / T206-2001 "public places airborne particles (PM10) measurement method can be inhaled - light scattering method"?? LD98-1996 industry standards in line with the Ministry of Labor "dust in the air concentration of light scattering assay?" in line with the Ministry of Railways industry standard TB / T2323-92 "railroad job site dust determination of the relative mass concentration and mass concentration conversion method. The instrument is suitable for rapid determination of public places, respirable particulate matter (PM10) concentrations, labor hygiene detect dust concentration and other industrial and mining production site, as well as environmental protection respirable dust concentration monitoring, but also for the efficiency of air purifiers Evaluation. Third, the specific use Application: 1. Suitable for industrial and mining production and the labor department 2. dust concentration measurement site health and epidemic prevention station monitoring public places respirable 3. Environmental environmental monitoring department of atmospheric particulates detect particulate matter pollution investigation 4. Municipal monitoring smoke 5. Scientific research, media and other aspects of performance test field test 6. The site dust concentration measurement, vent dust concentration monitoring 7. Pharmaceutical manufacturing test 8. 9. Occupational health and safety testing facility to clean the air of the place, precision instruments, test equipment, electronic components, food, medicine and other manufacturing process management 10. A variety of research, meteorology, public hygiene, industrial labor health engineering, air pollution research buildings or blasting dust detection 11. place; the site monitoring of workplace exposure 12. Indoor air quality testing four main features: direct reading of particulate matter concentration (mg / m3), 1 mins result; measurement fast, accurate, high sensitivity; designed from the school system, stable and reliable performance of the instrument ; with air curtain shield and clean air self-cleaning function to ensure no contamination of the optical system; the software automatically implement zero; with two-way communication with the computer functions, data processing via a PC, print out the curves and forms; having a concentration of particulate matter continuous monitoring, regular sampling and dust concentration exceeding the alarm and other functions;
