The Eipson oxygen probe's signal output module supports dual modes of 4-20mA/0-10V for switching, and is equipped with an RS485 communication interface to meet industrial Internet of Things applications. The sampling gas path features a bidirectional circulation design, effectively preventing coking and blockage in the detection chamber. The Eipson oxygen probe, certified by the EU ATEX explosion-proof and CE certification, can monitor residual oxygen concentration in converter gas recovery in the metallurgical industry, and reliably detect carbon potential in heat treatment fields. Its unique reference gas self-cleaning technology effectively resolves sulfur poisoning issues, maintaining detection accuracy at ±0.02%O2 across the entire lifecycle, a level in the industry.
