Product Overview
Our multi‑gas detector integrates Cl2 (Chlorine), H2 (Hydrogen), O2 (Oxygen) and H2S (Hydrogen Sulfide) detection functions in one compact device. It adopts high‑precision imported sensors to achieve fast response and stable measurement for toxic gas, combustible gas and oxygen deficiency/enrichment.
The device supports real‑time on‑site gas concentration display, over‑limit audible, visual and vibration multi‑mode alarm. Built‑in data logging function can store mass test records for later export and analysis. With explosion‑proof certification, it adapts to harsh industrial environment. Light‑weight handheld design is convenient for workers to carry during confined space entry, equipment maintenance and routine patrol inspection.
It effectively guards against chlorine leakage, hydrogen accumulation, oxygen lack and hydrogen sulfide poisoning risks in chemical, wastewater, petrochemical, metallurgy industries. It is an essential safety instrument for site personal protection.
