What Is a Recovery Period?

Recovery time refers to the desorption speed of the gas sensor to the measured gas, also known as the desorption time. The time from when the gas sensor is released from the detection gas until its resistance value returns to the resistance value in normal air is called the recovery time t _rec . In fact, commonly used gas sensors start from contacting and disengaging the detection gas, until their resistance value or resistance value increase reaches a certain time. The time required is defined as the response time and recovery time. ^[1]
