Description:
- H2S adopts high-selectivity independent electrochemical sensor, precisely detect toxic rotten-egg odor hydrogen sulfide produced by sewage sludge, manure and landfill degradation;
- CO2 uses stable NDIR non-dispersive infrared sensor, low zero drift, long service life, for measuring carbon dioxide accumulation from microbial fermentation in confined spaces.
Support dual sampling modes: standard diffusion sampling and optional 1L/min pump suction sampling, convenient for gas extraction from deep septic tanks, underground pipelines, biogas digesters and closed waste warehouses. Built-in stainless steel anti-corrosion filter screen blocks corrosive mist and sewage dust to protect sensors. LCD screen synchronously displays real-time concentration, gas name and over-limit alarm status of H2S and CO2.
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 applied to sewage treatment plants, biogas stations, waste landfills, livestock farms, underground pipeline maintenance and environmental law enforcement 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
