Product Description
OC‑850 is a rugged portable multi‑gas detector, designed to measure Ex, H₂S, CO, O₂ and CO₂ simultaneously. It supports diffusion sampling and optional pump suction sampling (1L/min). Equipped with imported high‑precision industrial sensors, the unit delivers stable and accurate real‑time gas concentration readings. LCD screen clearly shows gas concentration, gas type and alarm status. Sound, light and vibration triple alarm reminds operators of hazardous gas risks. With IP65 protection and Ex ib IIB T3 explosion‑proof certification, it is widely used for confined‑space entry, petrochemical, mining, sewage treatment and industrial site safety inspection. It can store up to 9999 groups of alarm records for on‑site safety traceability.
