Description:

OC-850 portable multi gas detector is customized to simultaneously detect H₂S Hydrogen Sulfide, NH₃ Ammonia, Odor Composite Odor, TVOC Total Volatile Organic Compounds, O₃ Ozone, 5 kinds of characteristic gases typical in odor pollution and environmental waste gas.
It supports dual sampling modes: built-in adjustable pump suction (1L/min) and diffusion sampling, which can draw gas from deep pipelines, manholes, landfill leachate wells and sealed containers for rapid quantitative detection.
  • H₂S & NH₃ adopt high-stability electrochemical sensors to quantify typical malodorous core toxic gases in sewage and breeding industries;
  • TVOC uses PID photoionization sensor to capture all volatile organic waste gas;
  • O₃ ozone electrochemical sensor monitors disinfection tail gas and photocatalytic oxidation by-products;
  • Odor composite odor is jointly characterized by the superposition data of H₂S+NH₃+TVOC to realize overall odor intensity grading evaluation.
Equipped with imported industrial-grade sensing elements, stainless steel anti-dust filter screen to protect the sensor from moisture and particle interference. LCD screen displays real-time concentration, gas name and alarm status, with 9999 groups alarm data storage. Ex ib IIB T3 explosion-proof and IP65 dustproof & waterproof grade, the machine can work continuously for 100 hours under diffusion mode, widely used in sewage treatment, landfill, livestock breeding, waste incineration, environmental law enforcement odor inspection and indoor disinfection residual ozone testing.

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
