Why the Industrial Safety Industry Is Moving Away from Galvanic O₂ Sensors 

Insights from Will Parrett, Teledyne DD-Scientific

The industrial safety market is undergoing a significant shift away from traditional lead-based galvanic oxygen sensors towards longer-life, lead-free amperometric technology. But what is driving this transition, how rapidly is adoption accelerating, and what are the implications for instrument manufacturers, distributors and end users?

Presented by Will Parrett of Teledyne DD-Scientific at Sensor+Test in Nuremberg earlier this year, ‘The Evolution of Lead-Free O₂ Sensors for Industrial Safety’ examines the evolution of oxygen sensing in industrial safety. It explores the impact of RoHS legislation, the limitations of conventional galvanic sensors, advances in modern amperometric technology, and changing expectations around performance, service life and total cost of ownership. The presentation also compares adoption trends across key global regions and considers how the oxygen sensing market is likely to evolve in the years ahead. 

Drawing on Teledyne DD-Scientific's expertise gained from manufacturing almost four million electrochemical gas sensors annually, together with Will's extensive experience in gas detection and instrumentation, this presentation provides practical insight into the technological, regulatory and commercial forces shaping the future of industrial safety and lead-free oxygen sensing.
