Description:
OC-850 portable multi gas detector is a customizable handheld toxic corrosive gas safety monitoring device, equipped with dual independent electrochemical sensor combination: H₂S Hydrogen Sulfide , NH₃ Ammonia.
Both H2S and NH3 adopt high-selectivity separated electrochemical sensors, effectively reduce cross interference between hydrogen sulfide and ammonia gas, accurately detect toxic malodorous gas decomposed by livestock manure, kitchen waste, sewage sludge and landfill waste.
This detector supports dual sampling modes: standard diffusion passive sampling and optional 1L/min pump suction active sampling, suitable for deep septic tanks, underground sewage wells, closed breeding houses and waste transfer stations gas extraction. Built-in stainless steel anti-corrosion filter screen blocks corrosive mist, manure dust and sewage particles to protect internal sensors. LCD screen synchronously displays real-time concentration, gas name and over-limit alarm status of H2S and NH3.
It holds Ex ib IIB T3 explosion-proof certification and IP65 dustproof & waterproof rating, 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 livestock breeding farms, sewage treatment plants, septic tanks, waste transfer stations, underground pipeline maintenance and environmental law enforcement malodorous 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
