Precautions for Use
● When charging the detector, please do so in a safe location and use a compliant charger with 5V/2A or higher.
● For first-time use, fully charge the battery before operation.
● During daily use, avoid exposing the detector to gas concentrations beyond its measurement range to prevent irreversible damage.
● Do not use the detector in harsh environments with extreme temperatures, high pressure, or excessive humidity. If ambient humidity is high, perform dehumidification filtration before detection.
● If sensor failure occurs, contact the manufacturer’s after-sales service.
● Under normal usage, the sensor's effective lifespan is 24–36 months. During this period, perform calibration checks every 6 months or 1 year (depending on the working environment) to ensure accurate gas monitoring. Sensors exceeding their lifespan or showing faults must be replaced.
