The Bühler Technologies GAS 222.10 Gas Sampling Probe is a high-performance industrial gas extraction device engineered and manufactured by Bühler Technologies (Germany). Serving as an indispensable primary interface in gas analysis architectures and Continuous Emission Monitoring Systems (CEMS), the GAS 222.10 reliably extracts representative gas samples from stacks, ducts, and process pipes for delivery to downstream analytical instrumentation.

Engineered for challenging process environments, the GAS 222.10 is specifically built to handle sample streams burdened with high particulate loads and elevated temperatures. Constructed using high-grade stainless steel (SS316Ti / 1.4571) or corrosion-resistant Hastelloy/PTFE wetted components, the probe prevents chemical degradation and mechanical wear when exposed to aggressive gases such as SO2, NOx, HCl, and CO. It incorporates an internal high-efficiency filter element (available in ceramic, PTFE, or stainless steel mesh) to trap particulate matter, ensuring clean gas delivery and protecting downstream analyzers from clogging or damage.

A key advantage of the Bühler GAS 222.10 is its user-friendly maintenance architecture. The design allows for rapid tool-free replacement of the filter element from the exterior without dismounting the entire probe assembly from the stack flange, minimizing maintenance downtime and enhancing personnel safety. Furthermore, the probe is equipped with a integrated backpurge connection, enabling automated high-pressure blowback to purge accumulated dust cake from the filter surface.

Manufactured in Germany to stringent quality standards, the Bühler Technologies GAS 222.10 is the premier sampling probe choice for environmental monitoring installations, industrial boilers, cement kilns, petrochemical refineries, and waste incineration facilities, guaranteeing sample integrity and long-term operational reliability.
