The gas detection industry use ETO sensor to detect Acetylene and Ethylene (Ethene). The problem using ETO sensors is that they don’t have good selectivity. They react to many other gases. If selectivity is an issue, the SemeaTech Acetylene (C2H2) and
Ethylene / Ethene (C2H4) sensors are way better. No comparison in the technology.
These high-performance Acetylene and Ethylene / Ethene sensors are offered by:
