Description:

OC-850 portable multi gas detector is customizable handheld industrial waste gas monitoring terminal, configured three matched sensor combination: VOC Volatile Organic Compound, NO₂ Nitrogen Dioxide, SO₂ Sulfur Dioxide.
  • VOC adopts high-sensitivity PID photoionization sensor for continuous detection of volatile organic pollutants produced by printing, coating and organic solvent volatilization;
  • NO₂ and SO₂ adopt separated independent high-selectivity electrochemical sensors, accurately detect acidic toxic flue gas discharged from smelting, chemical production and fuel combustion.

    This detector supports dual sampling modes: standard diffusion passive sampling and optional 1L/min pump suction active sampling, suitable for stack sampling, closed chemical workshops, coating production lines and environmental on-site sampling. Built-in stainless steel anti-corrosion filter screen blocks acid mist, solvent vapor and dust to protect internal sensors. LCD screen synchronously displays real-time concentration, gas name and over-limit alarm status of three gases.

    With Ex ib IIB T3 explosion-proof certification and IP65 dustproof & waterproof grade, triple sound-light-vibration over-limit alarm, stores up to 9999 groups alarm records. Wide working temperature -40℃~70℃, 100 hours long standby without pump. Widely applied to printing & coating factories, chemical enterprises, smelting workshops, environmental law enforcement waste gas sampling and industrial waste gas safety patrol.

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
