In pharmaceutical, semiconductor, and medical device manufacturing, airborne particle monitoring plays a critical role in maintaining GMP compliance, meeting ISO cleanroom classifications, and minimizing cross-contamination risks.
One of the most advanced and reliable solutions trusted by leading manufacturers today is the Remote Particle Counter (RPC) — an automated 24/7 monitoring technology from Lighthouse Worldwide Solutions, officially distributed and technically supported in Vietnam by GERA Hi-Tech.
What Is a Remote Particle Counter?
Unlike portable counters that must be manually moved between locations, remote particle counters are permanently installed at key points inside cleanrooms.
These devices operate continuously 24/7, measuring the number and size of airborne particles in real time. This enables early detection of contamination events that manual sampling could easily miss.
Each system integrates seamlessly with Environmental Monitoring Software (EMS) to automatically trigger alerts when particle concentrations exceed defined limits — ensuring accurate, consistent, and regulatory-compliant data.
How It Works
Remote particle counters detect particles using laser light scattering technology.
When particles pass through the laser beam, light is scattered and converted by a photodetector into an electrical signal proportional to particle size and count.
Depending on your facility’s setup, you can choose between:
-
Built-in pump models (ApexRp Series): Independent operation without a central vacuum system — ideal for facilities requiring flexible installation.
-
Vacuum-connected models (ApexR Series): Compact, quiet units that connect to your existing vacuum infrastructure — perfect for facilities with a stable central vacuum line.
Key Benefits of Remote Particle Monitoring
1️⃣ Real-Time Monitoring — Instant Contamination Detection
Continuous measurement captures short-term contamination spikes that daily manual checks often miss, ensuring compliance in ISO Class 5 sterile zones.
2️⃣ Reduced Human Error
Fixed-position devices eliminate the need for manual handling, reducing the risk of cross-contamination and airflow disruption in sensitive environments.
3️⃣ Automated Alerts & Centralized Data
The system sends real-time alerts when limits are exceeded and automatically logs data to BMS, LIMS, or EMS platforms, supporting traceability and audit readiness.
4️⃣ Global Regulatory Compliance
Continuous airborne particle monitoring has been required in aseptic areas (ISO 5) for over 20 years and remains the gold standard for environmental control and data integrity.
Smart Features for Accuracy & Reliability
Modern remote particle counters like the ApexR and ApexRp offer built-in self-diagnostics, alerting operators to potential issues such as:
-
Laser degradation or signal errors
-
Vacuum pressure anomalies or data interruptions
This ensures uninterrupted, accurate measurements and proactive maintenance to maintain compliance and data integrity.
SmartBracket™ — Intelligent Mounting for Data Integrity
Accurate data starts with proper installation.
The SmartBracket™ system by Lighthouse is purpose-built for cleanrooms, ensuring:
-
Fixed and accurate positioning — preventing location errors during maintenance.
-
Integrated ID chip for exact device mapping within the monitoring network.
-
Seamless cable and vacuum line concealment for a clean, hygienic, and watertight setup.
Three Flexible Mounting Options
