Description
Product Description
The Honeywell 2106B2312 is a high-temperature catalytic bead sensor from the Sensepoint HT series, designed to detect combustible gases in demanding industrial environments. Engineered for continuous operation up to +150 °C, it is ideal for high-temperature applications such as turbine enclosures, drying ovens, and solvent-based processing equipment. Its robust 316 stainless steel housing and poison-resistant design ensure reliable performance in harsh, contaminated atmospheres. The sensor provides fast, accurate readings over a wide detection range while maintaining compliance with ATEX and IECEx safety standards.
