Description:
- CO₂ adopts high-stability NDIR infrared sensor, anti-cross gas interference, long service life, used for carbon concentration monitoring in breeding farms and sewage facilities;
- O₂, NH₃, H₂S adopt high-selectivity independent electrochemical sensors, accurately detect oxygen deficit, irritating ammonia and toxic hydrogen sulfide gas produced by manure decomposition, sewage fermentation and waste degradation.
This detector supports dual sampling modes: standard diffusion sampling and optional 1L/min pump suction sampling, suitable for deep sewage tanks, underground confined spaces, livestock house interior gas extraction. Built-in stainless steel filter screen blocks corrosive mist and dust to protect sensors and extend service life. LCD screen synchronously displays four gas real-time concentration, gas name and over-limit alarm status.
Equipped with Ex ib IIB T3 explosion-proof certification and IP65 dustproof & waterproof grade, sound-light-vibration triple alarm, stores up to 9999 groups alarm records. Wide operating temperature range -40℃~70℃, 100 hours long standby under pump-off mode. Widely applied to livestock breeding farms, sewage treatment plants, waste transfer stations, underground pipeline maintenance, confined space operation pre-inspection and environmental law enforcement on-site sampling.
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
