Lasensor LSGY-101: The Standard for High-Pressure Gas Monitoring
https://www.lasensor-tech.com/
The Lasensor LSGY-101 is not a general-purpose particle counter; it is a highly specialized instrument engineered for one of the most challenging applications: monitoring particulate contamination in high-purity, high-pressure gas lines. This focus makes it an indispensable tool in industries where the delivery of pristine gases is non-negotiable.
Precision Measurement in Extreme Environments: High-Pressure Capability
The standout feature of the LSGY-101 is its ability to operate directly in gas lines with pressures ranging from 40 to 150 psi (2.8 to 10.3 bar). This eliminates the need for complex and potentially contaminating external diffusers or pressure-reducing systems. By sampling directly from the high-pressure environment, the device provides a more accurate and representative measurement of gas purity. This is critical in semiconductor manufacturing for process gases like nitrogen (N2) and argon (Ar), and in aerospace for testing hydraulic systems and fuel lines where contamination can lead to catastrophic failures.
Advanced Detection Technology: Multi-Channel Analysis and Laser Source
At its core, the LSGY-101 utilizes a robust, long-life laser diode as its light source. This technology offers superior stability and significantly reduces maintenance requirements and long-term cost of ownership compared to older lamp-based systems. The instrument provides an eight-channel analysis across a particle size range of 0.1 to 5.0 μm. This high-resolution, multi-channel capability allows quality control engineers to not only detect the presence of contamination but also to profile its nature. Understanding the size distribution of particles is key to diagnosing the source of contamination, whether it is from the gas source, the piping, or a failing filter.
Compliance and Connectivity: ISO Standards and Remote Data Management
Data integrity is paramount. The LSGY-101 is calibrated to and fully compliant with ISO 21501-4, the definitive standard for light-scattering airborne particle counters. This certification ensures that the data it produces is accurate, repeatable, and defensible during audits. Furthermore, the device is built for modern industrial ecosystems. It features integrated alarm functionalities that can be configured to trigger alerts when particle counts exceed predefined thresholds. Its data can be transmitted remotely via standard communication protocols, allowing for integration into a centralized facility monitoring system (FMS) for real-time oversight and historical trend analysis.
Labtron APC-3LS: The Portable Expert for Cleanroom Certification
The Labtron APC-3LS is a handheld, battery-powered particle counter designed for mobility and flexibility. It is the go-to instrument for professionals performing cleanroom validation, routine monitoring, and troubleshooting contamination issues on the factory floor.
Optimized for Field Use: Portability and Ergonomics
With its lightweight and ergonomic design, the APC-3LS is built for operators who need to move between multiple locations. It operates on a built-in rechargeable Li-ion battery, providing hours of continuous operation without being tethered to a power outlet. This is ideal for tasks such as certifying cleanrooms to ISO 14644-1 standards, which requires sampling at numerous locations, or for pinpointing the source of a contamination leak in a large facility. The device's self-cleaning function is another practical feature, purging the sensor and sample pathway to prevent cross-contamination between measurements and reduce manual maintenance.
Certified Performance: Six-Channel Detection and ISO Compliance
The APC-3LS features a six-channel detection system covering a particle size range from 0.3 to 10.0 μm at a flow rate of 0.1 CFM (2.83 L/min). While the flow rate is lower than larger benchtop models, it is perfectly suited for classification and spot-checking applications. The device is fully compliant with ISO 14644-1 requirements, making it a reliable tool for official cleanroom certification. Its ability to simultaneously display data across all six channels allows for a comprehensive and immediate understanding of the environmental conditions.
User-Centric Design: Data Management and Usability
Labtron has focused on making the APC-3LS easy to use. It stores thousands of measurements in its internal memory, which can be easily downloaded to a PC via USB for reporting and analysis. The interface is intuitive, allowing users to quickly set up sampling plans, define locations, and review historical data directly on the device.
