Description:

OC-850 portable multi gas detector is a customizable handheld industrial gas safety detector, equipped with four dedicated sensor combination: CO₂ Carbon Dioxide, O₂ Oxygen, NH₃ Ammonia, NO₂ Nitrogen Dioxide.
  • CO₂ adopts high-stability NDIR infrared sensor, strong anti-interference, long service life, for monitoring carbon concentration in farm, chemical workshop and exhaust emission;
  • O₂, NH₃, NO₂ adopt independent high-selectivity electrochemical sensors, precisely detect oxygen deficiency, irritant ammonia and toxic nitrogen dioxide generated by chemical reaction, fertilizer production, livestock manure decomposition and waste incineration.

    The device supports dual sampling modes: standard diffusion sampling and optional 1L/min pump suction sampling, suitable for deep pipeline, closed workshop, breeding house and sewage tank gas collection. Built-in stainless steel anti-corrosion filter screen blocks corrosive mist and dust to protect sensors. LCD screen synchronously displays four gas real-time concentration, gas type and over-limit alarm status.

    With Ex ib IIB T3 explosion-proof certification and IP65 dustproof & waterproof grade, triple sound-light-vibration alarm, stores up to 9999 groups alarm records. Wide working temperature range -40℃~70℃, 100 hours long standby without pump. Widely used in chemical fertilizer plants, livestock breeding farms, waste incineration stations, chemical workshops, environmental law enforcement sampling and confined space pre-operation safety inspection.

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
