Description:
OC-850 portable multi-gas detector is a highly customizable handheld industrial gas detection device, specially tailored for monitoring toxic corrosive gases including SO₂ Sulfur Dioxide, NO₂ Nitrogen Dioxide, HCL Hydrogen Chloride, meanwhile it can match combustible gas, O₂, CO₂, TVOC and other gases with 1~5 gas sensor combinations freely.
Compatible with Electrochemical, NDIR, PID and semiconductor high-precision sensors, the detector supports dual sampling modes: diffusion passive sampling and pump suction active sampling (flow rate 1L/min). Equipped with imported industrial-grade sensors and stainless steel filter screen, it effectively blocks dust and impurities to protect sensors and guarantee stable gas intake.
Equipped with clear LCD display, real-time show gas concentration, gas type and alarm status. Adopt Ex ib IIB T3 explosion-proof certification, IP65 waterproof & dustproof grade, support sound, light and vibration triple alarm. Built-in data storage for 9999 groups alarm records, wide operating temperature -40℃~70℃, long standby up to 100 hours, widely used in waste incineration plant, chemical plant flue gas inspection, environmental law enforcement, metallurgy and industrial pipeline leakage inspection.
Features:
- Detects 1–5 gases simultaneously
