Application scenarios
Petroleum and petrochemical, chemical plants, smelters, steel mills, coal mines, thermal power plants, medical research, pharmaceutical production workshops, tobacco companies, environmental monitoring, school research, building construction, fire alarm, sewage treatment, industrial gas process control, boiler rooms, garbage treatment plants, tunnel construction, oil pipelines, gas stations, underground gas pipeline maintenance, indoor air quality testing, hazardous materials Site safety protection, aerospace, military equipment monitoring, etc.
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.
