The PG-300 Series excels in demanding environments, offering robustness against light rain (with IP42 option) and seamless integration into networks for data acquisition.
The PG-300 Series from HORIBA represents a pinnacle in portable gas analyzer technology, engineered for professionals seeking accurate, multi-component gas measurements in diverse settings. This analyzer's compact form factor and lightweight construction—reduced by 20% from earlier iterations—make it an essential tool for on-site emissions testing, GHG monitoring, and process optimization.
Overview and Design Advantages
The PG-300 is tailored for simultaneous measurement of up to five gas components, delivering laboratory-grade precision in portable format. Its proven performance spans field investigations of environmental pollutants, stack emission evaluations, catalyst efficiency testing, and real-time process gas stream control. For enhanced durability, optional shock-resistant side guards and IP42 ingress protection safeguard against dust and water droplets, enabling reliable operation in challenging outdoor conditions like light rain (with necessary wiping for accuracy).
Key to its robustness is the IP42 rating, which protects against solid objects over 1mm and vertically falling water at up to 15 degrees tilt. This makes the PG-300 ideal for mobile applications where traditional analyzers fall short.
Measurement Principles and Technology
- NOx Detection**: Employs cross-modulation chemiluminescence detection (CLD) for high selectivity and accuracy.
- SO2, CO, and CH4 Detection**: Uses cross-modulation non-dispersive infrared absorption (NDIR) to minimize interference and ensure stable readings.
- CO2 Detection**: Standard NDIR method for reliable volumetric measurements.
- O2 Detection**: Flexible options including galvanic, zirconia, or paramagnetic methods to suit specific needs.
The cross-modulation technique alternates sample and reference gases, keeping the cell clean and reducing span drift for long-term stability. Unlike chopper methods, it eliminates zero drift and optical adjustments, enhancing reliability.
Models with CH4 capabilities are particularly valuable for biomass combustion analysis, fuel cell research, and GHG emission tracking, supporting sustainability efforts.
Operational Efficiency
Featuring a vibrant color LCD touch screen, the PG-300 offers intuitive navigation with features like screen capture, color trend graphs, and an integrated operation guide. Warm-up is expedited to 30 minutes, with a timer for automated pre-heating, saving valuable time in the field.
The analyzer boasts a 95% efficient NOx converter for precise measurements and an energy-efficient design that cuts power use by up to 35%. Data handling is streamlined via an SD memory card slot for storage and Ethernet for network integration, allowing real-time monitoring and CSV file recording through dedicated software.
Software Capabilities
The PG-350 software, compatible with Windows (Vista, XP, 7+), provides a user-friendly interface for data acquisition, graphing, and control of NO/NOx valves. Users can switch modes manually or automatically, view all component values, and customize graph ranges from 3 to 480 minutes. Install on multiple computers with a license based on the PG's MAC address, and run instances for simultaneous multi-unit operation.
Global Compliance and Versatility
Supporting multiple languages (English, Chinese, Korean, German, French, Russian, Japanese) and certified by TÜV (EU), China, Korea, Japan, MCERTS (UK), and GOST (Russia), the PG-300 meets international standards.
It serves as an effective backup or cross-verification tool for stationary systems like the ENDA-5000 Stack Gas Analysis System, enabling continuous measurements up to 5 days (depending on conditions) via branched sampling lines.
