Description:
OC-850 portable multi gas detector is customized for greenhouse gas detection with combined CH4(Methane), CO2(Carbon Dioxide), N2O(Nitrous Oxide). All three gases adopt high-stability NDIR infrared sensors, effectively avoid cross interference, realize long-term stable measurement of low-concentration biogas and landfill exhaust pollutants.
Support two sampling modes: diffusion and optional pump suction (1L/min flow). Built-in LCD screen synchronously displays real-time concentration, unit and alarm status, stores up to 9999 groups of alarm records for greenhouse gas emission filing and environmental data traceability.
With Ex ib IIB T3 explosion-proof grade and IP65 protection, 300g lightweight portable design, 100 hours standby without pump. Widely applied in biogas stations, waste landfills, agricultural farms, waste treatment plants, environmental law enforcement greenhouse 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
