Description:

OC-850 portable multi gas detector is a customizable handheld industrial comprehensive waste gas monitoring terminal, equipped with three matched sensor combination: NH₃ Ammonia, Odor Total Malodor, CO₂ Carbon Dioxide.
  • NH3 adopts independent high-selectivity electrochemical sensor to detect pungent ammonia decomposed by livestock manure, sludge and organic waste;
  • Odor malodor uses high-sensitivity MOS metal oxide semiconductor sensor to identify mixed composite stench from fermentation waste gas;
  • CO2 adopts stable NDIR infrared sensor with low zero drift and long service life, measuring carbon dioxide accumulation produced by microbial fermentation in closed breeding houses and sewage tanks.

    Support dual sampling modes: standard diffusion sampling and optional 1L/min pump suction sampling, suitable for deep septic tanks, underground sewage wells, closed livestock houses and waste transfer stations gas collection. Built-in stainless steel anti-corrosion filter screen isolates corrosive mist, manure dust and water vapor to protect 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 alarm, stores up to 9999 groups alarm records. Wide working temperature -40℃~70℃, 100 hours long standby without pump. Widely used in livestock breeding farms, sewage treatment plants, septic tanks, kitchen waste disposal workshops and environmental law enforcement malodor sampling 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
