Description:

OC-850 portable multi gas detector is customizable handheld indoor & industrial air safety monitoring device, configured four matched sensor combination: CO₂ Carbon Dioxide, CH₂O Formaldehyde, NH₃ Ammonia, TVOC Volatile Organic Compound.
  • CO2 adopts high-stability NDIR infrared sensor, low zero drift and long service life, for detecting CO2 accumulation caused by poor ventilation;
  • CH2O and NH3 adopt independent high-selectivity electrochemical sensors, accurately measure formaldehyde released from decoration materials and irritant ammonia from raw materials or sewage;
  • TVOC adopts high-sensitivity PID photoionization sensor, continuously detect total volatile organic pollutants in workshop and newly renovated rooms.

    This detector supports dual sampling modes: standard diffusion sampling and optional 1L/min pump suction sampling, convenient for gas sampling inside closed cabinets, decoration rooms and production workshops. Built-in stainless steel filter screen blocks dust and particle pollutants to protect sensors. LCD screen synchronously displays real-time concentration, gas name and over-limit alarm status of four gases.

    It has 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 used in newly renovated buildings, office buildings, furniture factories, coating workshops, indoor environmental acceptance and industrial waste gas 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

Stainless steel filter for better gas flow and sensor protection
