The Bühler GAS 222.30 Heated Gas Sampling Probe is a high-performance industrial sample extraction unit from the flagship GAS 222 series by Bühler Technologies GmbH (Germany). This probe is engineered specifically for demanding industrial applications characterized by heavy dust loads, high process temperatures, and requiring minimal maintenance downtime in Continuous Emission Monitoring Systems (CEMS) and industrial process control.

A key structural advantage of the GAS 222.30 model is its tool-free, quick-release filter cover mechanism (Easy-Lock System). This design allows maintenance engineers to inspect and replace the internal filter element (available in Ceramic or SS316L stainless steel) effortlessly without requiring additional tools. This significantly reduces maintenance downtime while protecting technicians from contacting hot component surfaces.

Equipped with an integrated self-regulating electric heating element, the probe head maintains a constant operating temperature of up to 200°C (392°F). Continuous heating prevents water vapor condensation, acid dew point drop, and line corrosion, preserving sample gas integrity before delivery to downstream analyzers. Combined with an integrated pneumatic blowback connection for automated filter purging, the Bühler GAS 222.30 provides reliable, uninterrupted 24/7 sampling performance for thermal power, cement, chemical, and waste-to-energy facilities.
