Main features:
It can directly read the mass concentration of particulate matter (mg/m3), output the result in 1 minute, or set the sampling time according to user needs;
Fast, accurate measurement, and high detection sensitivity;
Designed a self calibration system with stable and reliable instrument performance;
Equipped with air curtain shielding and self-cleaning function for clean gas, ensuring that the optical system is not contaminated;
Implemented software automatic zeroing;
It has the function of bidirectional communication with computers, and can process data and print curves and tables through a PC;
It has multiple functions such as continuous monitoring of particulate matter concentration, timed sampling, and alarm for excessive dust concentration;
This instrument is suitable for rapid determination of inhalable particulate matter (PM10) concentration in public places, detection of dust concentration in labor hygiene aspects such as industrial and mining production sites, monitoring of inhalable dust concentration in the field of environmental protection, and evaluation of purification efficiency of air purifiers. In recent years, over a thousand LD-3C instruments have been used throughout the country and have received high praise from users.
The instrument complies with industry standards such as the WS/T206-2001 "Method for determination of inhalable particulate matter (PM10) in the air of public places - light scattering method" issued by the Ministry of Health, the LD98-1996 "Method for determination of dust concentration in the air by light scattering method" issued by the Ministry of Labor, and the TB/T2323-92 "Method for conversion of relative mass concentration and mass concentration of dust determination in railway workplace air instruments" issued by the Ministry of Railways, as well as the "Hygiene Specification for Central Air Conditioning and Ventilation Systems in Public Places" issued and implemented by the Ministry of Health's Health Supervision Document [2006] No. 58.
