The inner body of an amperometric gas sensor requires occasional replacement. More frequently, the electrolyte in the sensor's membrane body will need replenished and the membrane body itself, replaced. Replacement/refilling times vary based on individual application conditions and knowing when to conduct these tasks is often down to the experience of operators.
METTLER TOLEDO amperometric gas sensors with Intelligent Sensor Management (ISM) technology offer diagnostic tools that show, in days remaining, when inner body and membrane body replacement or electrolyte refilling should be performed. These tools, such as the Dynamic Lifetime Indicator, help to ensure that you avoid any unplanned downtime in your monitoring and control processes.
