QRJ-400 portable aerosol generator Introduction: The QRJ-400 portable aerosol generator is exquisitely designed, easy to carry, and has strong stability in emitting particles. It includes two patented technologies (ZL2021103675403 and ZL2021103671953). Suitable for quality control and calibration of instruments and equipment, and can be used in mobile testing vehicles. It is a universal aerosol diffuser widely used in aerosol and powder science, industrial processes, and quality control.. Used for the verification and calibration of low concentration dust measuring instruments/PM2.5 mass concentration measuring instruments, meeting and complying with the following regulations: JJG846-2015 "Verification Regulations for Dust Concentration Measuring Instruments" HJ618-2011 "Determination of PM10 and PM2.5 in ambient air by gravimetric method" HJ93-2013 (for PM10 and PM2.5) "Technical Requirements and Testing Methods for Environmental Air Particle Samplers" JJF 1659-2017 "Calibration Specification for PM2.5 Mass Concentration Measuring Instruments" Features: 1. Adopting imported high-precision mass flow controller to regulate flow, with precise control and flow stability ≤ 1% FS; 2. Support the setting of gas flow rate and dilution gas flow rate, with adjustable flow range (0-50) L/min, and adjustable concentration range according to different media; 3. Built-in precision aerosol calibrator, real-time feedback of concentration occurrence, achieving closed-loop dynamic control of walking; 4. Equipped with a built-in magnetic stirring system to prevent particle solution settling and maintain uniformity; 5. Equipped with a built-in heating and drying device and a dedicated water outlet device, it effectively removes moisture from wet aerosols, prevents particle pollution and blockage, and improves continuous working life; 6. The instrument inlet is equipped with a purification and drying system to remove impurities and moisture from the gas source; 7. The instrument provides three calibration interfaces (expandable), with good consistency in concentration across each interface, with a deviation of ≤ 5%; 8.
