Dust particle detector: a precise ruler for environmental cleanliness

In the fields of precision manufacturing and life sciences, air cleanliness is the lifeline of product quality. A tiny speck of dust can cause chip short circuits, drug contamination, and sterile packaging failure - and the dust particle detector is the key sentinel guarding this invisible defense line.

Core principle: Scientific dialogue between light and particles

When dust particles in the environment pass through a precision optical cavity at high speed, a highly stable laser beam (lifetime>30000 hours) emits characteristic scattered light on the particles. The core sensor of the dust particle detector captures these light signals, and their intensity strictly corresponds to the particle size. Through real-time signal processing, the device can synchronously and accurately count the particle concentration of six standard particle size channels (0.3 μ m to 10.0 μ m), with an error strictly controlled within ± 30% (taking 0.5 μ m as an example), providing a reliable basis for cleanliness grading.

Technical advantage: From passive detection to active control

Multi channel synchronous analysis: completing the counting of six particle sizes in a single sampling, with efficiency far exceeding that of single channel equipment.

High precision environmental compensation: Equipped with temperature and humidity sensors (± 0.3 ℃, ± 2% RH) and air pressure sensors (± 1hPa), it automatically corrects the impact of environmental variables on the detection results.

Intelligent Cleanliness Determination: Built in global mainstream standards such as ISO 14644 and GMP, automatically calculates 95% confidence level (UCL) and outputs purification level, reducing the risk of human error.

Flexible data management: supports USB drive export, wireless transmission, and cloud docking (optional), with a storage capacity of 100000 pieces to meet long-term traceability needs.

Industrial grade reliability: wide working range (0-40 ℃/10-75% RH), anti-interference optical path design, repeatability error<10%.

Targeting industry pain points and providing efficient solutions

Pain point 1: Low detection efficiency

The traditional method requires measuring different particle sizes in batches, which is time-consuming and prone to missing pollution events.

Solution: Six particle size channel synchronous detection, 2.83L/min high flow sampling, 10 second fast response.

Pain point 2: Doubts about data credibility

Manual recording is prone to errors, and environmental fluctuations affect accuracy.

Solution: Automatic environmental compensation+UCL calculation, strictly following JJF1190-2008 calibration specifications to ensure the authority of the report.

Pain point 3: High compliance audit pressure

Paper records are difficult to trace, and dynamic environments are difficult to monitor.

Solution: Electronic storage of 100000 pieces of data, which can be associated with time/location information, and generate GMP/ISO compliance reports with just one click.

Application scenarios with global coverage

Pharmaceutical sterility assurance: Real time monitoring of GMP workshop, laboratory, and filling line environment to prevent particle contamination of drugs.

Electronic manufacturing yield control: Monitor semiconductor cleanrooms and hard disk production lines to reduce scrap rates caused by dust.

Food packaging safety: Clean packaging area testing for dairy and meat products to eliminate the risk of foreign object contamination.

High end manufacturing and research: aerospace component assembly, optical lens production, biosafety laboratory environmental control.

Filter efficiency verification: On site testing of HEPA/ULPA filters for interception efficiency and leakage point.
