Description:
OC-850 portable multi gas detector is customizable handheld industrial gas detection device, specially configured with CO₂ Carbon Dioxide + SF₆ Sulfur Hexafluoride dual NDIR infrared sensor combination, and supports matching O2, combustible gas, TVOC and other gases to form 1~5 gas detection schemes.
Both CO2 and SF6 adopt high-stability NDIR non-dispersive infrared sensors, effectively resist cross gas interference, long service life, no poisoning risk, perfectly fit power substation SF6 leakage inspection and greenhouse gas CO2 concentration monitoring scenarios.
This detector supports dual sampling modes: diffusion passive sampling and optional 1L/min pump suction active sampling, convenient for deep pipeline, confined space and electrical cabinet internal gas sampling. Built-in stainless steel filter to block dust and moisture to protect sensors. LCD screen synchronously displays real-time concentration, gas name and alarm state.
With 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 operating temperature -40℃~70℃, 100 hours long standby without pump. Widely used in power substation electrical equipment inspection, greenhouse carbon monitoring, environmental law enforcement, waste treatment plant and industrial pipeline gas leakage patrol.
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
