MiniMeta Portable SO2 Gas Detector with Imported Electrochemical Sensor, 2-Year Standby & IP68 Waterproof
MiniMeta is a cost-effective portable single gas detector that meets global hazardous area safety standards. It is powered by a replaceable 3.6V non-rechargeable dry battery, delivering 2 years of standby without extra charging or calibration work. The sensor and battery can be swapped independently to extend service life. This SO2 version adopts an imported electrochemical sensor, with a measuring range of 0–100ppm, 0.01ppm resolution, ≤±2–5%FS accuracy and 15–30s T90 response time. It provides adjustable multi-type alarms and complete real-time data display. Matching DKM docking station and DKS software are available for batch maintenance and data archiving.
Sulfur dioxide is a pungent toxic air pollutant produced by fuel combustion and industrial manufacturing, which causes varying degrees of respiratory damage to human bodies under different concentrations, with 100ppm as the IDLH critical value.
Combustion: coal power plants, refineries, ships Metallurgy: copper/zinc/lead smelters, cement plants Chemical: sulfuric acid & fertilizer factories Food: dried fruit fumigation, wine brewing Natural: volcanic vents, hot springs
0.3–1ppm: odor and mild mucosal irritation 1–5ppm: coughing and weakened lung function 5–10ppm: severe bronchial irritation 10–50ppm: acute breathing difficulty >50ppm: permanent lung injury or death
Power plant flue gas inspection, petroleum refineries, non-ferrous smelters, pulp & paper mills, food fumigation workshops, urban environmental monitoring, chemical plants, marine vessels, mining and laboratory fume hoods.
