Product Overview 

The OC-850 portable flue gas detector is a multi-functional industrial gas detection instrument designed for flue gas analysis, exhaust emission inspection and on-site environmental safety monitoring. It supports detection of multiple gases such as CO, CO₂, O₂, NO2, SO₂, combustible gas and toxic gas, making it suitable for boilers, industrial furnaces, chimneys, exhaust pipes, chemical plants, power plants, waste incineration facilities and environmental protection inspection scenarios.
This detector adopts a portable handheld design and supports pump suction or diffusion sampling modes according to different application requirements. The built-in sampling pump can actively draw air or flue gas into the sensor chamber, helping to shorten response time and improve detection stability. It is equipped with imported industrial gas sensors, ensuring reliable performance even in complex industrial environments.
The OC-850 features an LCD screen that clearly displays gas concentration, measurement units, alarm status and battery level. When the gas concentration exceeds the preset threshold, the device will trigger sound, light and vibration alarm reminders. With compact size, light weight and easy operation, it can be used for routine safety patrols, flue gas inspections, emission testing and confined space detection.

Key Features 

  1. Multi Gas Detection Capability
    Supports detection of CO, CO₂, O₂, NO2, SO₂, combustible gas and toxic gas, suitable for flue gas and industrial emission analysis.
  2. Pump Suction or Diffusion Sampling
    Dual sampling modes allow flexible use in different detection scenarios. Pump suction mode is especially suitable for flue gas pipelines, exhaust ports and confined space sampling.
  3. Imported Industrial Sensors
    Equipped with high-performance sensors to ensure stable detection data and reliable long-term operation.
  4. Clear LCD Display
    Real-time display of gas concentration, measurement unit, alarm status and battery level for easy on-site reading.
  5. Sound, Light and Vibration Alarm
    When the concentration exceeds the set threshold, the detector will activate audible, visual and vibration reminders to warn operators in time.
  6. Portable Handheld Design
    Compact body and lightweight design make it easy to carry during field inspections, boiler room checks and environmental monitoring.
  7. Suitable for Flue Gas and Exhaust Detection
    Ideal for boiler flue gas, industrial furnace exhaust, chimney emission, chemical plant waste gas and environmental protection inspection.
  8. Easy Operation and Maintenance
    Simple menu operation, clear data display and convenient daily maintenance.
