OC‑905 pump‑suction portable SO₂ sulfur dioxide gas detector with imported electrochemical sensor, 100000‑group data storage & USB export, two‑stage sound‑light alarm, Ex ib IIC T4 Gb explosion‑proof for power plant, smelting factory and industrial toxic‑gas safety monitoring.
Description:
OC‑905 portable pump‑suction sulfur dioxide(SO₂) gas detector adopts famous‑brand original imported electrochemical sensor and ultra‑low‑power 32‑bit microprocessor. Equipped with built‑in sampling pump with stable 300 ml/min flow rate for active suction sampling of sulfur dioxide toxic gas. Benefiting from four‑layer circuit wiring, intelligent algorithm, multi‑point calibration and temperature compensation, the instrument delivers stable performance and high‑accuracy measuring results. The 2.5‑inch dot‑matrix LCD screen directly displays real‑time SO₂ concentration data. It supports maximum 100 000 groups measurement‑data storage, and historical data can be exported to computer via USB cable. Two‑stage adjustable audible‑visual alarm will trigger when sulfur dioxide concentration reaches preset alarm threshold. Featuring all‑English operation menu, aluminum‑alloy metal housing, Ex ib IIC T4 Gb explosion‑proof grade and IP54 protection grade, this handheld detector is widely used in thermal power plant, metallurgical smelting plant, petrochemical industry, sulfuric‑acid workshop, waste incineration plant, environmental‑protection emergency‑inspection and other occasions requiring SO₂ toxic‑gas safety monitoring.
