The Bühler Technologies GAS 222.17 Heated Gas Sampling Probe is a high-precision extraction unit designed for demanding industrial gas analysis and Continuous Emission Monitoring Systems (CEMS) by Bühler Technologies (Germany). Belonging to the acclaimed GAS 222 Series, the GAS 222.17 stands out by incorporating a temperature-regulated electrical heating element equipped with an integrated PT100 temperature sensor alongside an integrated process shut-off valve.

By utilizing an integrated PT100 temperature sensor connected to an external temperature controller, the GAS 222.17 allows for exact temperature control and monitoring of the probe body up to 200°C. Maintaining precise thermal regulation prevents sample gas cooling, eliminating water vapor fallout and acid dew point condensation when sampling corrosive gases such as SO2, NOx, HCl, or HF. This protects heated sample lines and analytical detectors from corrosive degradation and filter element clogging.

Additionally, the GAS 222.17 features an integrated mechanical shut-off valve (ball valve) located directly on the probe body. This isolation valve allows maintenance technicians to isolate the sample line directly at the process stack flange without interrupting main plant operations. Filter element inspection, cleaning, or replacement can be performed safely and rapidly without exposing operators to high-temperature or toxic process gases.

Constructed from heavy-duty, corrosion-resistant wetted materials including stainless steel 1.4571 (SS316Ti), Hastelloy, or PTFE coatings, the GAS 222.17 includes a high-capacity particulate filter element and a backpurge connection for automated compressed air blowback cleaning. Manufactured 100% in Germany to strict ISO quality management protocols, the Bühler Technologies GAS 222.17 is the premier sampling probe choice for power generation, cement manufacturing, petrochemical plants, and waste incinerator emission monitoring.
