  • Page 133: Conversion Of The Concentration Data

    Response time The time a sensor needs from the start of a measurement until the measurement value has reached a certain percentage of the final value. Usually, the response time is measured until 90% of the measurement value (t ) or 50% has been reached In some sources, the response time is also referred to as increase time.
