Description:

OC-850 portable gas detector is customized to detect H₂S Hydrogen Sulfide and NH₃ Ammonia, the two core malodorous and toxic gases in sewage treatment, breeding industry, waste disposal and municipal pipeline industries.

Both gases adopt exclusive high-stability electrochemical sensors with strong gas selectivity and low cross interference, which can realize real-time quantitative detection of gas concentration.

This device supports two sampling modes: built-in pump suction (flow rate 1L/min) and diffusion sampling. The pump suction hose can be extended into manholes, sludge tanks, breeding barns, garbage bins and narrow confined spaces to trace tiny leakage points. The LCD screen synchronously displays the concentration value, unit and alarm state of H2S and NH3, and supports storing up to 9999 groups of alarm data for environmental filing and hidden danger traceability.

It has Ex ib IIB T3 explosion-proof certification and IP65 dustproof and waterproof grade. Under diffusion working mode, the continuous working time can reach 100 hours, which is perfectly suitable for daily fixed-point patrol inspection and on-site evidence collection of odor pollution by environmental supervision departments.

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
