Analysis and Application of Handheld Laser Particle Counter Technology

In the field of modern industry and technology, air cleanliness is no longer an optional standard, but a core element related to product quality, process safety, and even life and health. Dust particle counters, especially handheld laser particle counters, have become indispensable precision "sentinels" for safeguarding clean environments.

Core principle: Laser illuminates the microscopic world

Its core is based on the principle of light scattering. A highly stable semiconductor laser emits a precise beam of light, which scatters when particles in the air pass through the sampling area. The intensity of scattered light strictly corresponds to the particle size, and the photodetector captures these signals. After real-time analysis by a high-speed processor, the number and concentration of particles in different particle size channels (such as 0.3 μ m, 0.5 μ m, etc.) can be accurately counted, and the results are displayed intuitively on a large-sized touch screen.

Technical advantages: Portable and intelligent, precise and efficient

Compared to traditional bulky devices, handheld design brings revolutionary breakthroughs:

Flexible and maneuverable: It can conduct real-time sampling at any key point such as dust-free workshop, equipment interior, and air supply outlet, solving the blind spot of fixed point monitoring.

Powerful battery life: The built-in high-capacity lithium battery supports continuous operation for ≥ 8 hours, meeting the needs of long-term multi-point detection.

Intelligent and efficient: capacitive touch screen, real-time bar chart, temperature and humidity synchronous monitoring, 95% UCL automatic calculation, data is clear at a glance. Standard audit tracking and multi-level user management to meet strict compliance requirements.

Data worry free: Massive storage space (starting from 4GB) combined with USB flash drive export, WiFi remote transmission, and Bluetooth printing ensures complete and traceable data.

Strict and reliable: Complies with mainstream clean standards such as JJF1190, GB/T6167, ISO, GMP, etc., with a sampling flow accuracy of ± 5% and a repeatability error of<10%, providing a solid basis for decision-making.

Key application: Clean Guard Across Industries

Pharmaceutical and Bioengineering: Key links of GMP certification (dynamic/static monitoring), sterile filling area, laboratory environment validation.

Semiconductor and electronic manufacturing: Cleanliness control in wafer workshops and lithography areas to prevent particle contamination and reduce yield.

Medical Health: Operating Room ICU、 Infection control in biosafety laboratories and disinfection supply centers.

Precision manufacturing and clean room: Maintain ISO Class level to ensure the production of precision instruments and optical components.

HVAC and purification: efficient filter leakage testing, purification equipment performance verification, and daily maintenance.

Direct Pain Point: Terminator of Traditional Monitoring

The industry is facing long-term pain points: high cost and limited coverage of fixed equipment; Third party detection has slow response and data lag; Manual recording is prone to errors and difficult to trace. Handheld laser particle counter provides the perfect solution:

Cost optimization: One machine replaces multiple fixed devices, significantly reducing investment.

Efficiency leap: instant response, independent completion of multi-point and high-frequency detection.

Compliance assurance: Detailed data recording and audit tracking functions make it easy to cope with strict audits.

Risk prevention and control: Real time alarm (with cleanliness level threshold set) helps to intervene quickly and prevent problems before they occur.
