Discover the CEMS-PRE225HSP heated sampling probe – ideal for accurate gas sampling in high-temperature, high-dust environments. Perfect for CEMS applications in power, waste, and heavy industries.
In industrial emission monitoring and environmental compliance, accuracy, durability, and reliability are critical. That’s where the CEMS-PRE225HSP heated sampling probe comes into play. Designed for extreme combustion environments, this probe is the ideal solution for continuous emission monitoring systems (CEMS) in power plants, incinerators, chemical processing, and more.
Whether dealing with high temperatures, high dust loads, or corrosive gases, the CEMS-PRE225HSP offers a robust design, automatic maintenance features, and precision filtration, making it one of the most reliable sampling solutions in today’s market.

The CEMS-PRE225HSP is equipped with an adjustable heating system ranging from 120°C to 180°C, which helps maintain a stable internal environment to prevent condensation and ensure accurate gas sampling. This wide heating range allows flexibility for different gas compositions and operating conditions.
Built with 2µm and 5µm stainless steel sintered filters, along with ceramic filtering options, the CEMS-PRE225HSP effectively removes particulates from sample gases before analysis. This ensures high purity of gas samples and protects downstream analyzers from contamination.
To minimize maintenance and extend service intervals, the CEMS-PRE225HSP integrates an automatic blowback system using clean, oil-free compressed air or nitrogen gas (0.4–0.8MPa). This function removes dust and debris from the filter element, maintaining consistent flow and performance.
With an IP65 protection rating, the sampling probe is fully resistant to dust and water ingress, making it suitable for outdoor or harsh industrial environments. Its corrosion-resistant materials ensure long-lasting durability under high-temperature and high-humidity conditions.
The probe is compatible with DN50 mounting flanges, allowing easy integration into a variety of exhaust systems. The modular design also allows customization to fit specific industrial needs or CEMS configurations.
The CEMS-PRE225HSP heated sampling probe is ideal for a wide range of industries, including but not limited to:
Thermal power plants – For SO₂, NOx, and CO₂ emissions monitoring
Waste incineration – For VOCs and dioxin measurement
Cement manufacturing – In kiln and preheater exhaust analysis
Steel and metallurgy plants – For stack gas sampling under high dust and heat
Chemical and petrochemical sectors – For emission compliance and process optimization
