What Do You Know About 4-Gas Detectors | What Is Their Service Life?
1, The sensor type determines the basic lifespan
The core component of the four in one gas detector is the gas sensor, and its principle directly affects its lifespan
(1) Electrochemical sensors (for detecting carbon monoxide, hydrogen sulfide, etc.) have a lifespan of about 1-2 years. Due to the gradual drying of the internal electrolyte, they will naturally wear out even if not in use.
(2) Catalytic combustion sensor (detecting combustible gases): with a lifespan of about 2-3 years, it is greatly affected by high concentrations of combustible gases in the environment.
(3) Infrared sensor (detecting carbon dioxide, etc.): has a lifespan of about 3-5 years, high stability, and is not easily affected by interference from other gases.
(4) PID sensor (detecting organic gases such as VOCs): The lifespan is about 3-5 years, but it is important to avoid high humidity environments.
2, The lifespan of the equipment itself
(1) Circuit board: A circuit board with reliable design and sufficient materials can generally guarantee a service life of 3-5 years.
(2) Battery: The battery in a portable four in one gas detector can generally last for about 2 years.
3, Factors affecting service life
(1) Usage environment: The four in one gas detector can shorten the service life of sensors and equipment when used in harsh environments such as low temperature, high temperature, and high humidity.
(2) High concentration gas: Long term detection in an over range state can cause serious damage to the instrument and shorten its service life.
(3) Maintenance: Lack of maintenance can lead to a shortened service life of the detector.
4, Methods to extend service life
(1) Regular calibration: It is recommended to calibrate the four in one gas detector once a month or quarter to ensure measurement accuracy.
(2) Regular maintenance: including cleaning sensors, checking battery levels, replacing aging components, etc.
(3) Proper use and storage: Avoid using in harsh environments and store in a dry, ventilated, and dust-free place.
(4) Battery management: Regularly check the battery level to avoid battery leakage or damage to the instrument.
