New lead-free oxygen sensors comply with new RoHS legislation while providing an enhanced level of precision and durability

Oxygen sensors with lead will be banned under Restriction of Hazardous Substances (RoHS) legislation from 2024. DD-Scientific has developed lead-free oxygen sensors that are not only compliant with the new legislation, but also provide considerably improved performance and lifespan. 

DD Scientific’s lead-free sensors work in a similar way to current toxic electrochemical sensors so OEMs will not have to develop new and complex drive circuitry. They are stable over periods of 8 years and over and, unlike lead based sensors, they are ideal for use in acid gas streams. 

The new sensors are available in DD Scientific’s 4 Series general purpose industrial package, the 5 Series package for emissions monitoring and combustion gas analysis and in a miniature DceL package for easier gas monitor portability.
