Remote Particle Counters

Key Features

Real-Time Monitoring Capabilities: Remote particle counters provide continuous surveillance of air quality in critical manufacturing and research environments, delivering immediate alerts when particle concentrations exceed predefined thresholds. The instruments transmit data securely to centralized software platforms, enabling cleanroom managers to monitor multiple locations simultaneously and respond quickly to contamination events. This real-time functionality supports proactive contamination control strategies and reduces the risk of product quality issues in pharmaceutical and biotechnology operations.​

Compact and Non-Intrusive Design: The small footprint of remote air particle counters allows installation in space-constrained locations without interfering with manufacturing operations or disrupting unidirectional airflow patterns. These instruments are typically mounted directly to equipment or facility infrastructure using isokinetic probes and short sample tube lengths to ensure representative sampling. The fixed installation approach eliminates the need for repeated manual sampling, reducing personnel traffic in critical zones and minimizing contamination risks associated with human intervention.​

ISO and Regulatory Compliance: Remote particle counters are designed to meet stringent performance requirements outlined in ISO 21501-4 for light-scattering airborne particle counters, ensuring accurate and reproducible measurements. Annual calibration procedures verify critical parameters including particle size accuracy, counting efficiency, flow rate consistency, and false count rates. The instruments support compliance with ISO 14644-1 cleanroom classification standards and pharmaceutical manufacturing regulations, with automated reporting capabilities that facilitate regular certification audits.​

Multi-Channel Particle Sizing: Advanced remote particle counters offer multiple user-selectable size channels, typically ranging from 0.3 µm to 25 µm, allowing simultaneous monitoring of different particle size distributions. This multi-channel capability is particularly important for pharmaceutical applications that require monitoring of both 0.5 µm and 5.0 µm particles as specified in regulatory guidance. The laser light scattering detection principle enables accurate sizing and counting of particles across the full measurement range.​

Data Integrity and Reliability: Remote particle counters incorporate best-in-class data buffering systems that protect against data loss during network outages or communication interruptions. The instruments maintain secure data transmission protocols and support 21 CFR Part 11 compliance requirements for electronic records in regulated pharmaceutical environments. Flow sensors and environmental controls ensure measurement accuracy and consistency across varying operational conditions.​

Integration with Environmental Parameters: Many remote particle counter models are compatible with temperature and humidity sensors, providing comprehensive environmental monitoring from a single instrument platform. This integrated approach simplifies facility monitoring system architecture and ensures that air quality data is captured alongside critical environmental parameters that influence cleanroom performance. Continuous monitoring of temperature, humidity, and particle concentrations supports maintenance of optimal conditions for sensitive manufacturing and research processes.​

Applications of Remote Particle Counters

Pharmaceutical Manufacturing: Remote particle counters are essential tools for environmental monitoring in pharmaceutical, biopharmaceutical, and radiopharmaceutical manufacturing facilities worldwide. These instruments provide continuous monitoring of aseptic processing areas, filling lines, and other critical zones where products cannot be terminally sterilized. The technology supports risk-based contamination control strategies by serving as an early warning system to detect and prevent contamination events that could compromise product quality or patient safety.​​

Cleanroom Classification and Certification: Particle counters are used to classify cleanrooms according to ISO 14644-1 standards, which define cleanliness classes based on particle concentration per cubic meter of air. Remote air particle counters enable ongoing verification of cleanroom performance between formal certification events, ensuring continuous compliance with classification requirements. The instruments support testing in both operational and at-rest states, providing data for routine monitoring and media fill simulations.​

Biotechnology Research Facilities: Remote particle counters for labs maintain controlled environments necessary for cell culture, protein production, and other sensitive biotechnology applications. The continuous monitoring capability protects valuable research samples and products from particulate contamination that could compromise experimental results or process yields. Laboratory-grade instruments often incorporate flow rates and sensitivity ranges optimized for smaller-volume controlled spaces.​​

Semiconductor and Electronics Manufacturing: Cleanroom particle monitoring is critical in semiconductor fabrication facilities where submicron contamination can cause defects in microelectronics production. Remote particle counters detect particles down to 0.3 µm or smaller, supporting the stringent cleanliness requirements of advanced semiconductor processes. The technology monitors ultrapure water systems, lithography areas, and other critical manufacturing zones.​

Medical Device Manufacturing: Precision parts manufacturing for medical devices requires controlled environments to prevent particulate contamination of implantable products and sterile devices. Remote particle counters provide continuous verification that manufacturing environments meet regulatory requirements for medical device production. The instruments support validation of cleaning procedures and environmental control systems.​

Food and Beverage Industry: Critical filling and packaging operations in food and beverage manufacturing benefit from particle monitoring to ensure product safety and quality. Remote air particle counters monitor aseptic filling lines and controlled packaging environments where microbial and particulate contamination must be minimized. The technology helps maintain compliance with food safety regulations and industry quality standards.​
