What are Dust Particles?  

Dust particles are solid or liquid micro-particles suspended in the air, with particle sizes ranging from 0.1 microns to millimeter-scale, including dust, microorganisms, and pollutants. In industries with strict cleanliness requirements such as pharmaceuticals, electronics, and food, their concentration and particle size distribution directly affect product quality. For example, particles larger than 5 microns may cause drug contamination or electronic component failures, while micron-level particles serve as primary carriers for microorganisms, threatening the safety of aseptic environments.  

What is the Main Role of an Airborne Particle Counter?  

As a core device for clean environment monitoring, an airborne particle counter can accurately detect the number of particles of different sizes (0.3–25 microns) per unit volume, supporting the classification of cleanroom grades (such as 10,000-class or 100-class clean areas) according to standards like ISO 14644 and GMP. Its core value lies in real-time monitoring of particle concentration, evaluation of air conditioning system efficiency, and providing data support for enterprises to meet regulatory requirements such as FDA and Chinese Pharmacopoeia. It is an essential tool for cleanroom compliance verification.  

How to Achieve Intelligent and Precise Particle Monitoring in Cleanrooms?  

Traditional monitoring relies on manual operations, suffering from data lag and large errors. Lumeley's developed Particle Counter Pro LM-GPro series breaks through industry pain points with three innovations:  

• Intelligent Sampling

Three flow rates (28.3 L/min to 100 L/min) adapt to different scenarios, with high-precision sensors ensuring a particle capture rate ≥98%.  

• Human-Machine Interaction

A 10.1-inch touchscreen supports SOP mode presetting, automatically calculating the minimum sampling volume specified in pharmacopoeias, with data real-time upload via Wi-Fi.  

• Durable Design

A full stainless-steel body resists disinfectant wiping, with an IP54 protection rating suitable for high-frequency disinfection environments in pharmaceutical workshops.

1. Floating Bacteria Sampler LM-AC Series 

Based on the Anderson impact principle, the 25/37-hole impact plate simulates human respiratory tract deposition, efficiently capturing microorganisms by impacting airborne bacteria onto agar surfaces at high speed. Compared with traditional methods, dynamic rehydration technology shortens the culture cycle by 20%–30%. Sterilizable sampling heads comply with international standards like USP<797>, suitable for microbial concentration monitoring in hospital operating rooms and food dust-free workshops.  

 2. Air Volume Hood FLY-1  

 China's pioneering mass-produced Pitot tube-type airflow hood uses a 16-sensor matrix for multi-point pressure averaging, with a measurement error ≤±2% FS, exceeding national standard requirements. The 3.2kg lightweight design supports single-person operation, with a detachable flexible hood adapting to different air outlets. Calibrated by a 0.5-class standard wind tunnel before shipment, it is a core tool for cleanroom fresh air debugging and air conditioning system energy optimization. 

3. Microbiological Limit Meter LM-G308 

Designed according to the Chinese Pharmacopoeia, this negative pressure filtration device features an oil-free diaphragm pump for 0–600mL/min flow adjustment, supporting 50–1000mL sample testing. Modular filter heads are autoclavable and compatible with 0.22μm PES membranes, meeting microbial limit inspection and sterilization needs for pharmaceuticals and medical devices, significantly improving laboratory efficiency.  

4.Intelligent Bacteria Collector LM-P50 

Used with bacteria collection culture vessels, it solves bubble interference in traditional negative pressure filtration through directional peristaltic pressure technology, supporting automatic rinsing liquid addition (up to 5 times) to eliminate sample bacteriostasis. The 7-inch touchscreen integrates 20 standard test procedures, with three-level password protection ensuring data non-tampering, making it a compliant choice for aseptic testing in pharmaceutical enterprises.
