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:

  • Real-time synchronous measurement of H2S, NH3, Odor, TVOC and O3; support flexible configuration of 1~5 different gas sensors according to actual demands
  • Dual sampling structure available for selection: natural diffusion detection mode and 1L/min constant flow pump suction sampling mode
  • Imported dedicated industrial sensors & odor sensing probes, response time controlled within 10 seconds with high measurement stability
  • Sound, light and vibration three-dimensional alarm reminder system, ensuring effective early warning in open-air garbage yards and humid sewage workshops
  • High-definition LCD screen displays gas concentration value, gas name and current alarm working state synchronously for intuitive viewing
  • Built-in data storage chip, capable of saving 9999 groups of alarm records to facilitate on-site operation record filing and later data trace analysis
  • Ex ib IIB T3 explosion-proof structure plus IP65 waterproof and dustproof shell, adapting to humid, dusty and corrosive outdoor odor detection environments
  • Excellent long-lasting power performance: 100 hours of continuous working time when the built-in air pump is closed
  • Freely switchable Chinese and English system interface, compatible with multiple common measurement units: PPM, %VOL, %LEL, mg/m³
  • Wide operating temperature range of -40℃ ~70℃, maintaining stable detection effect under high temperature and low temperature field conditions
  • Internal stainless steel filter effectively blocks water mist and solid impurities, protects each sensor component and keeps smooth gas intake
