Backed by extensive industry experience, our systems are designed using three core measurement technologies to deliver reliable, accurate, and compliant emission monitoring solutions for industrial applications.
Dilution Extractive System
The Dilution Extractive System is an advanced emission monitoring solution in which the sample gas is extracted directly from the process stack and instantly diluted with clean, dry zero air at the probe itself. This immediate dilution reduces the sample gas temperature and moisture content at the source, ensuring reliable and stable measurement while protecting downstream analyzers from harsh process conditions. By eliminating the requirement for heat-traced sample lines, the system significantly reduces installation complexity, maintenance requirements, and operational costs. Its simplified design makes it highly suitable for applications where maintaining sample integrity is critical, while also ensuring accurate monitoring with minimal hardware infrastructure. The Dilution Extractive System is widely preferred for demanding industrial environments requiring dependable performance, low maintenance, and long-term operational reliability.
Hot-Wet / cold dry Extractive System
The Hot-Wet / Cold-Dry Extractive System is designed for reliable emission monitoring in high-temperature and high-dust industrial applications. The sample gas is extracted through a heated probe and filter assembly, then transported via heat-traced sample lines to maintain temperature and prevent condensation before reaching the analyzers. An automatic blow-back arrangement ensures smooth operation in dusty environments by minimizing filter blockage and maintenance. This system is ideal for monitoring pollutants that may condense or chemically react at lower temperatures, ensuring accurate, stable, and continuous emission measurements in demanding process conditions.
In-Situ Measurement System
The In-Situ Measurement System is a direct emission monitoring solution where the analyzer is installed directly on the stack or duct, eliminating the need for sample extraction and conditioning systems. By measuring gases directly in the process stream, the system provides fast response time, low maintenance, and reliable real-time monitoring. In-Situ systems are available in Cross-Duct configurations for average measurement across the entire duct and Probe-Type configurations for point-specific analysis. RAYS offers a wide range of advanced In-Situ analyzer models for monitoring critical parameters such as SO₂, NOₓ, CO, CO₂, HCl, Dust, O₂, NH₃, and other process emissions, ensuring accurate and continuous environmental compliance across various industrial applications.

SAMPLING SYSTEMS
Sample Conditioning Systems
At RAY, our Sample Conditioning Systems (SCS) are engineered to ensure that a representative, clean, and timely sample reaches your analyzer—every time. A well-designed SCS is critical not only for achieving accurate analytical results but also for protecting sensitive analyzer components and maximizing system reliability. With modern analyzers becoming increasingly precise and sensitive, the importance of an optimized SCS has never been greater. Industry experience shows that up to 90% of analyzer inaccuracies and maintenance issues originate from poor sample handling and conditioning. That’s why RAY focuses on delivering robust, application-specific solutions.
Sampling Probes
At RAY, we specialize in the design, engineering, and supply of high-performance sampling probes for Continuous Emission Monitoring Systems (CEMS) and process analyzers. Our probes are built to extract representative, reliable samples directly from harsh industrial environments while ensuring long-term durability and measurement accuracy. Sampling is the first and most critical step in any analyzer system. An improperly designed probe can lead to inaccurate readings, frequent maintenance, and analyzer damage. RAY’s probe solutions are engineered to overcome these challenges by delivering clean, conditioned, and consistent samples under all operating conditions.
Sampling Pumps and Coolers
RAY offers high-performance sample pumps designed to ensure reliable extraction and transport of gas samples from the process point to the analyzer. Our pumps are engineered for continuous operation in demanding industrial environments, delivering stable flow rates and consistent sample integrity. Our sample gas coolers are designed to reduce sample temperature and remove moisture before it reaches the analyzer. This is critical in preventing condensation-related errors and protecting sensitive analyzer components.
