Description:

OC-850 portable multi gas detector is customized to detect four typical toxic flue and waste gas: H₂S Hydrogen Sulfide, NH₃ Ammonia, CO Carbon Monoxide, SO₂ Sulfur Dioxide. All four gases adopt separate high-selectivity dedicated electrochemical sensors, which effectively reduce cross-interference between mixed flue gas and realize stable quantitative detection of low-concentration industrial tail gas.
  • SO₂ & CO: Core characteristic pollutants of boiler combustion and incineration flue gas, key items for desulfurization and incomplete combustion risk monitoring;
  • NH₃ & H₂S: Typical malodorous irritant gases from sewage denitrification, breeding industry and sludge decomposition, the main supervision objects of odor pollution control.
The device supports built-in pump suction (1L/min flow rate) and diffusion dual sampling modes. The sampling hose can be directly inserted into flue pipes, boiler exhaust outlets, workshop ventilation ducts and sewage reaction tanks to extract gas samples for rapid on-site testing. The LCD color screen synchronously displays the concentration value, unit and alarm status of four groups of gas, and supports storing 9999 groups of alarm data for environmental emission filing and hidden danger traceability.

With Ex ib IIB T3 explosion-proof grade and IP65 dustproof & waterproof shell, the continuous working time can reach 100 hours under diffusion mode. Widely used in waste incineration power plants, thermal power boiler rooms, chemical fertilizer plants, sewage denitrification workshops, environmental law enforcement exhaust sampling and industrial waste gas supervision.

Features:

  • Detects 1–5 gases simultaneously
  • Compatible with electrochemical, NDIR, PID, and semiconductor sensors
  • Flexible gas configuration for different detection environments
  • Pump suction or diffusion sampling mode (optional)
  • LCD display showing gas concentration, gas type, and alarm status
  • High-precision imported sensors for accurate measurement
  • Built-in self calibration and zero calibration functions
  • Temperature and pressure compensation for reliable readings
  • Two-level alarm system: sound, light, and vibration
  • Adjustable alarm set points
  • One-key factory reset function
  • Large capacity rechargeable lithium polymer battery
  • Durable PC + TPE housing: anti-slip, waterproof, dustproof, explosion-proof
  • Stainless steel filter for better gas flow and sensor protection
