Product Overview 

OC-850 customizable portable multi gas detector supports 1~5 arbitrary gas collocation, this model is configured with five independent high-precision electrochemical sensors to detect CO Carbon Monoxide, NO₂ Nitrogen Dioxide, SO₂ Sulfur Dioxide, O₃ Ozone, H₂S Hydrogen Sulfide.
All five gases adopt separated imported electrochemical sensors, effectively reduce cross interference between corrosive, oxidizing, acidic and malodorous mixed toxic gases. Dual sampling modes optional: standard diffusion sampling and built-in 1L/min pump suction sampling, applicable for stack flue gas sampling, waste incineration site inspection, chemical workshop patrol and environmental law enforcement on-site monitoring.
Front stainless steel filter screen blocks acid mist, smoke dust and organic vapor to protect internal sensors. LCD screen synchronously displays real-time gas concentration, gas name and alarm status, supports PPM, mg/m³ multi-unit switching, Chinese & English menu free switch.
With Ex ib IIB T3 explosion-proof grade and IP65 dustproof waterproof rating, triple sound-light-vibration alarm, stores up to 9999 groups alarm records. It achieves 100 hours ultra-long standby when pump is turned off. Widely used in waste incineration plants, smelting factories, chemical enterprises, sewage treatment plants, coating workshops and atmospheric pollution sampling inspection.

Key Features 

  1. Multi Gas Detection Capability
    Supports detection of CO Carbon Monoxide, NO₂ Nitrogen Dioxide, SO₂ Sulfur Dioxide, O₃ Ozone, H₂S Hydrogen Sulfide, 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.
